統合失調症の症状には、幻覚、妄想、まとまりのない会話、意欲の低下、認知機能の困難などがあります。初期の変化だけでは統合失調症とは診断されません。診断は臨床評価によって行われ、差し迫った危険、重度の混乱、または基本的なニーズを満たせない場合は、緊急の支援が必要です。
要点
- 統合失調症の症状 には、知覚、信念、会話、意欲、思考の変化が含まれます。1つの症状や検査結果の異常だけでは診断は確定できません。
- 初期兆候 には、引きこもり、睡眠不足、成績の低下などがありますが、これらは特定の疾患に限られるものではありません。役立つ場合は7日間にわたって変化を記録してもよいですが、新たな精神病性体験がある場合は評価を受けるのを先延ばしにしないでください。
- 幻覚 とは、対応する外的刺激がないのに知覚が生じることです。入眠時や覚醒時にのみ起きる体験は、日中に持続する幻聴とは臨床的な意味が異なります。
- 陰性症状 には、感情表出、会話、意欲、喜び、社会参加の低下が含まれます。これは一般に説明される5つの領域であり、その人が怠けている証拠ではありません。
- 診断の時期 相違点は、DSM-5-TRでは一般に6か月以上の持続的な障害が必要とされるのに対し、ICD-11では特徴的な症状が少なくとも1か月続くことが求められる点です。どちらの基準に達する前でも、支援を受け始めるべきです。
- 血液検査 医学的要因を調べ、治療の安全性をモニタリングできます。統合失調症を診断できる、妥当性が確認された定期的な血液検査の基準値はありません。
- 緊急の支援 差し迫った自傷のおそれ、本人が実行に移す可能性のある危険な命令、重度の混乱、または飲食ができない状態がある場合は必要です。英国では、差し迫った危険がある場合、999または112に電話してください。
- 治療 は通常、薬物療法、心理的ケア、実践的な支援を組み合わせます。NICEは、精神病に対する個人CBTとして、少なくとも16回の計画的なセッションを推奨しています。
どのような統合失調症の初期兆候に対して評価を受けるべきですか？
統合失調症の初期兆候 には、社会的な引きこもり、機能の低下、異様な体験、睡眠や思考の変化などが含まれることがありますが、いずれも単独では診断の根拠になりません。日常生活の2つ以上の領域に影響する新たな兆候のまとまりが見られたら、特に本人が怯えていたり、これまでできていたことができなくなっていたりする場合は、注意が必要です。
その人の通常の状態からの変化 は、ある行動が他人にとって異様に見えるかどうかよりも重要です。たとえば、以前は楽しんでいた3つの活動への参加をやめ、会話についていくのに苦労し、疑い深さが次第に強まっている仮想の学生は、昔から一人でいることを好んできた人とは異なる評価が必要です。
睡眠の乱れは手がかりであり、結論ではありません。試験期間中に毎晩3時間しか眠らない仮想の成人は、疲労によって集中力が低下したり、通常とは異なる知覚を経験したりすることがあります。当社の 睡眠不足と検査 のガイドでは、睡眠歴によって付随する検査所見の解釈も変わる理由を説明しています。
KantestiはAI血液検査アナライザーです は付随する検査所見の原因を説明できますが、初期の行動変化が統合失調症を示すかどうかは判断できません。当社の 会社と目的 では当社の役割を説明しています。7日間の症状記録は臨床医に共有するものであり、それによって精神科の診断が下されるわけではありません。
NICEは、苦痛や社会的機能の低下に、一過性または軽減した精神病症状、あるいは特定のその他のリスク指標が伴う場合、遅滞なく紹介することを推奨しています（NICE, 2014）。懸念されるエピソードが1回あった後の評価で、うつ病、トラウマ、物質の影響、または発症しつつある精神病性障害が見つかることがありますが、自動的に統合失調症という診断名が付くわけではありません。
幻覚はどのように感じられ、ほかに何が幻覚を引き起こしますか？
幻覚 は、対応する外的刺激がないのに生じる感覚体験です。統合失調症では幻聴がよく見られますが、幻覚はほかの病気でも生じます。評価では少なくとも3つの問いを分けて考えます。何が起きたのか、いつ起きたのか、そして苦痛や危険を伴うのかです。
聴覚体験は、語りかけ、会話、音楽、指示のように聞こえることがあり、頭の中または外から聞こえるように感じられる場合があります。24時間の間に体験が完全に目覚めているときに起きるか、どれくらい続くか、環境音で説明できる可能性があるかを、臨床医が尋ねることがあります。頭の中で聞こえるからといって、自動的に無害とは限りません。
睡眠への移行期に生じる体験 は、持続する覚醒時の幻覚とは異なり、精神病性障害がなくても起こることがあります。異様な知覚が寝入りばなや目覚めるときに限って起きる場合、日中の過度の眠気や関連症状から、睡眠に関する評価が必要と考えられることがあります。当社の ナルコレプシー検査の解説 では、臨床医が睡眠に関する手がかりを1つだけでなく複数用いる理由を説明しています。
感覚障害、死別、薬、酩酊、離脱、神経疾患も幻覚の原因となることがあります。新たな視覚体験と2日間にわたる注意力の変動がある仮想の72歳の人は、晩発性統合失調症と決めつけるのではなく、せん妄やその他の医学的原因について評価を受ける必要があります。
Command voices require a safety assessment, not an automatic assumption that someone will act on them. Ask about 3 concrete factors: what the voice says, whether the person feels compelled to obey, and whether they can stay safe; commands involving harm with intent or inability to resist warrant immediate help.
妄想は心配や風変わりな信念とどう違いますか？
Delusions are beliefs held with strong conviction despite compelling contrary evidence, assessed within the person's cultural and social context. Clinicians examine at least 3 dimensions—conviction, openness to alternatives, and consequences—rather than diagnosing schizophrenia because a belief sounds unfamiliar or implausible to an observer.
Persecutory delusions can involve beliefs that others are monitoring, targeting, or plotting against the person; referential delusions can involve interpreting ordinary events as personally directed messages. A hypothetical person changing travel routes 4 times to avoid an alleged surveillance team may need assessment of both the belief and the resulting disruption.
Real threats must not be dismissed as delusions. Abuse, discrimination, stalking, and exploitation can occur, including in people with established psychiatric diagnoses; 1 unusual detail does not invalidate an entire account, and a clinician should investigate plausible safety concerns rather than use psychiatric history as a shortcut.
Mood timing changes the differential diagnosis. A hypothetical adult who develops grandiose beliefs during 5 days of markedly increased energy and little need for sleep may have a manic episode; our mood swings and laboratories explains why testing can address contributors without distinguishing bipolar disorder from schizophrenia.
Repeated confrontation often damages trust without resolving a firmly held belief. A supporter can use 2 steps: acknowledge the fear or distress, then offer practical help without endorsing the explanation; discussing whether the person is eating, sleeping, or feeling safe is usually more useful than trying to win an argument.
統合失調症の陰性症状とは何ですか？
Negative symptoms of schizophrenia describe reductions in ordinary emotional expression, speech, motivation, pleasure, or social engagement. These 5 domains are commonly termed blunted affect, alogia, avolition, anhedonia, and asociality; they describe difficulties in functioning, not character flaws or a person's capacity to care.
Avolition means difficulty initiating or sustaining purposeful activity, even when the person understands its value. A hypothetical adult may want to prepare breakfast yet remain unable to begin for 2 hours; simply adding pressure can miss problems with initiation, planning, fatigue, or anticipation of reward.
Reduced expression does not reliably reveal the intensity of someone's internal feelings. A person who gives 1-word answers or shows little facial movement may still feel affection, anxiety, or sadness; communication should allow extra time and avoid interpreting a quiet response as indifference or refusal to participate.
Secondary negative symptoms can arise from depression, sedating medicines, ongoing paranoia, substance use, or a low-stimulation environment. Our low motivation laboratory guide addresses selected medical contributors, but 1 thyroid or vitamin result cannot distinguish primary negative symptoms from these overlapping causes.
Pleasure can be uneven: some people struggle more with anticipating enjoyment than with enjoying an activity once it starts. A practical experiment is 1 short, supported activity chosen by the person, followed by asking how it actually felt; the result guides support, not a diagnosis or a promise of recovery.
統合失調症に伴うことがある認知や会話の変化には、どのようなものがありますか？
Cognitive changes can affect attention, working memory, processing speed, and planning, while disorganized speech can make connections between ideas difficult to follow. These are distinct problems: an assessment should separate at least 2 issues—trouble organizing thought and trouble performing a task under everyday demands.
Disorganized speech may involve frequent derailment, answers loosely connected to questions, or speech that becomes difficult to understand. A hypothetical conversation moving through 4 unrelated topics can raise concern, but language proficiency, hearing, anxiety, developmental differences, and the person's usual communication style must be considered before interpreting it.
Working-memory difficulty can make multistep tasks unexpectedly hard. Someone may remember the first of 3 instructions but lose the remaining steps; offering one instruction at a time, using reminders, and reducing distractions are accommodations that can help before the precise cause of the difficulty is established.
A lifelong attention pattern is different from a recent decline. Our adult ADHD symptom guide explains why a history extending back to childhood matters; a new deterioration over 2 months should not be explained away by an unconfirmed ADHD label.
At Kantesti, we treat laboratory explanations of fatigue or brain fog as separate from psychiatric diagnostic reasoning. A hypothetical person with corrected anemia who remains unable to follow a 10-minute conversation still needs follow-up; improvement in a laboratory value does not prove that cognitive symptoms have resolved or identify their cause.
成人の統合失調症の症状は、年齢によってどのように異なりますか？
Schizophrenia symptoms in adults vary in onset, severity, and impact; the same symptom can have different implications at different ages. A first presentation at 22 and a first presentation at 72 both need assessment, but later onset increases the need to investigate medical, neurological, medication, and sensory contributors.
Schizophrenia commonly begins in late adolescence or early adulthood, but age alone cannot confirm or exclude it. For a hypothetical 24-year-old, clinicians may reconstruct the relationship between missed work, unusual beliefs, substance exposure, and sleep across several months instead of relying only on what happens during 1 appointment.
First-onset psychosis in an older adult should prompt careful review of medicines, cognition, physical health, hearing, and vision. Our 高齢者の薬剤影響ガイド explains why a newly added treatment or a dose change 2 weeks earlier can be a more useful clue than a broad psychiatric label.
People can have episodic worsening, persistent difficulties, or substantial improvement with treatment and support. A hypothetical adult managing work for 5 years before a recurrence does not erase the original diagnosis; equally, a first psychotic episode does not establish what the person's long-term course will be.
Schizophrenia is not a split personality, and psychosis does not mean someone is inherently violent. Risk assessment concerns specific circumstances—such as intoxication, severe fear, access to means, or expressed intent—not a diagnosis alone; 1 frightened presentation should not define how family members or services treat a person.
臨床評価では、どのように統合失調症と診断しますか？
Schizophrenia is diagnosed clinically, using the symptom pattern, duration, functioning, and exclusion of better explanations—not a blood test or online checklist. DSM-5-TR generally requires at least 6 months of continuous disturbance; ICD-11 requires characteristic symptoms for at least 1 month, with additional requirements in both systems.
DSM-5-TR requires at least 2 characteristic symptoms during a significant portion of a 1-month period, or less if successfully treated, with at least one being delusions, hallucinations, or disorganized speech. It also requires functional deterioration and a longer course of disturbance; the criteria are not a self-scoring tool.
ICD-11 uses a different structure and requires at least 2 characteristic symptoms, including at least one from its core group, present most of the time for 1 month or more. WHO's clinical requirements emphasize the overall presentation and differential diagnosis rather than mechanically translating every DSM rule into ICD terminology (WHO, 2024).
Assessment often takes more than 1 conversation, particularly when symptoms are new or the history is unclear. With appropriate consent and attention to confidentiality, information from relatives, previous records, and the person's own account can clarify timing; lack of agreement between accounts should be explored rather than treated as proof that someone is unreliable.
Support should not wait for a 6-month diagnostic threshold to pass. A first episode may initially receive a broader working diagnosis while treatment and investigation proceed; our 責任あるAIの原則 reflect why automated laboratory interpretation must not substitute for this evolving clinical judgment.
血液検査で統合失調症を検出したり、症状の原因を特定したりできますか？
No routine blood test diagnoses schizophrenia, and normal results do not rule it out. Laboratories serve 2 different purposes in this setting: investigating plausible medical contributors and establishing physical-health or medication-safety baselines; neither purpose turns a biomarker panel into a schizophrenia screening test.
Testing is selected from the history and examination, rather than ordered as an unlimited panel. A clinician may consider a CBC, electrolytes, kidney or liver tests, thyroid function, B12, or other investigations; our 甲状腺ホルモンについての解説 shows why 2 related thyroid measurements can be more informative than one isolated result.
B12 deficiency can contribute to neurological or cognitive symptoms, sometimes without marked anemia. In a hypothetical example, B12 of 160 pg/mL against that laboratory's 200–900 pg/mL interval warrants medical review; our 境界域のB12の解釈 explains why assay ranges and follow-up testing matter, without claiming that deficiency explains every symptom.
KantestiはAI血液検査の読み方プラットフォームです that can help explain these 2 laboratory roles without converting results into a psychiatric label. We encourage readers to bring the original report, medicine list, and symptom timeline to the assessing clinician; an interpretation should preserve uncertainty when symptoms and laboratory findings do not fit neatly together.
Research measurements of immune activity, metabolism, proteins, or genetic associations are not validated routine diagnostic thresholds for schizophrenia. A result showing 1 elevated inflammatory marker may reflect many unrelated processes; commercial-sounding claims that a panel can confirm psychosis should be questioned for independent validation and clear intended-use limits.
統合失調症に似た症状を呈する可能性がある病気には、どのようなものがありますか？
Psychosis can arise from mood disorders, substances, medicines, delirium, and neurological or other medical illnesses, as well as schizophrenia-spectrum disorders. Timing is central: symptoms developing over 2 days with fluctuating attention require a different workup from a gradual change over several months with preserved alertness.
Delirium typically involves disturbed attention and an acute, fluctuating course, and it can include hallucinations or unusual beliefs. A hypothetical person alternating between coherent conversation and marked disorientation over 24 hours needs urgent medical assessment; a pre-existing schizophrenia diagnosis does not make delirium impossible.
New seizures, abnormal movements, reduced consciousness, or rapid cognitive decline can raise concern for an inflammatory brain disorder or another neurological cause. Our autoimmune encephalitis workup explains how MRI, EEG, and cerebrospinal fluid may contribute; 1 positive serum antibody does not independently establish that diagnosis.
Rare medical causes deserve targeted investigation when the accompanying pattern fits, not blanket screening of everyone. Severe episodic abdominal symptoms plus neurological or psychiatric changes can prompt a porphyria workup; our porphyria testing explanation describes why a correctly timed urine test can matter more than 1 general blood panel.
Substance and medication histories should be specific and nonjudgmental. Ask what was taken, approximate amounts, and timing during the preceding 48 hours and earlier weeks; cannabis, stimulants, corticosteroids, and withdrawal states can change diagnostic reasoning, while a negative toxicology screen cannot exclude every exposure or every detection-window limitation.
統合失調症の症状には、どのような場合に緊急の支援が必要ですか？
Seek emergency help for immediate danger, suicidal intent, dangerous commands someone may act on, severe confusion, or inability to meet basic needs. In the UK, call 999 or 112 for an emergency; new psychotic symptoms without immediate danger still warrant prompt assessment rather than waiting for a routine laboratory appointment.
Possible catatonia needs urgent assessment, including when someone becomes unusually immobile, stops speaking, maintains unusual postures, or refuses fluids. A hypothetical adult drinking nothing for 24 hours and remaining largely motionless should not be managed as simple low motivation; fever, rigidity, or reduced responsiveness further increases concern.
Sudden speech difficulty, one-sided weakness, collapse, or a severe new headache requires emergency medical evaluation. Our 脳卒中の警告徴候 explain why 1 new focal neurological sign should not be attributed to psychiatric illness, even when hallucinations or a previous mental-health diagnosis are also present.
New psychosis after childbirth is a medical emergency, particularly with little sleep, rapidly changing mood, or confused behavior. If a parent develops these changes 1 week after delivery, seek urgent assessment and ensure both parent and infant have safe support; do not wait to see whether the symptoms fit schizophrenia.
If there is no immediate danger, contact a local crisis service, primary-care clinician, or early-intervention service promptly. In England, NHS 111 offers a mental-health option; in the US, 988 provides crisis support and 911 handles immediate danger, while readers elsewhere should use local emergency or crisis services and avoid leaving an immediately unsafe person alone when it is safe to remain.
精神病を経験している可能性のある人を、どのように支援できますか？
Help by listening calmly, checking immediate safety, and offering a specific route to assessment, rather than arguing about beliefs or announcing a diagnosis. A useful first conversation covers 3 practical needs: whether the person feels safe, whether they are eating and sleeping, and what assistance they would accept.
Short sentences and a quieter environment can make communication easier when attention is strained. Offer 2 realistic choices, such as contacting a clinician together or accompanying the person to an assessment, instead of several simultaneous demands; avoid crowding, sudden touching, or using threats to force cooperation.
Validate distress without confirming an unverified explanation. If someone believes their food is being tampered with, a supporter can acknowledge the fear and offer an acceptable meal while arranging help; asking how much they have eaten in the last 24 hours identifies a practical risk without requiring a debate about the belief.
A brief timeline can improve an appointment more than a long list of labels. Record 5 kinds of information: observed changes, approximate onset, sleep, substances or medicine changes, and effects on daily functioning; distinguish what you directly observed from what someone else reported, and ask the person's permission whenever possible.
Kantestiの プライバシーとデータに関するガイダンス is relevant when accompanying laboratory reports contain sensitive personal information. Share only what is needed and seek consent where possible; having access to 1 family member's report does not automatically authorize uploading their records, and emergency safety concerns should be addressed through clinical services rather than an AI tool.
初回の精神病エピソードの後には、どのような治療が役立ちますか？
Treatment for first-episode psychosis commonly combines antipsychotic medication, psychological interventions, and practical support, tailored to diagnosis, preferences, and safety. NICE recommends individual CBT with at least 16 planned sessions and family intervention where appropriate; treatment should address everyday functioning as well as voices or delusions.
Medication choice is a shared clinical decision, including discussion of metabolic effects, movement symptoms, sedation, hormonal effects, and cardiovascular considerations. NICE advises treating an antipsychotic prescription as an explicit individual trial, generally assessing response after 4–6 weeks at an optimum dose while reviewing tolerability throughout (NICE, 2014).
Psychological treatment does not require the clinician to endorse a delusion or tell someone that their experience is imaginary. CBT for psychosis explores distress, interpretations, coping, and functioning; NICE describes family intervention as at least 10 planned sessions over 3 months to 1 year, adapted to the family's circumstances.
Clozapine is recommended for treatment-resistant schizophrenia after inadequate response to 2 adequate antipsychotic trials, subject to clinical assessment and local requirements. The APA guideline also recommends clozapine when suicide risk remains substantial despite other treatments (APA, 2020); our clozapine safety monitoring guide explains why monitoring is treatment-specific.
Recovery goals should be personal and measurable rather than limited to symptom counts. A hypothetical first goal might be returning to 2 supported study sessions weekly or preparing a regular meal; occupational, educational, housing, and social support can address barriers that medication alone does not remove, and prescriptions should never be changed through an automated laboratory interpretation.
統合失調症のケアに身体の健康状態の確認が含まれるのはなぜですか？
Physical-health checks identify medication effects and health risks that deserve care independently of psychiatric symptoms. NICE recommends baseline assessment and repeat glucose or HbA1c and lipid testing at 12 weeks, 1 year, and annually during antipsychotic treatment; individual medicines and existing conditions may require additional monitoring.
Weight, blood pressure, movement symptoms, nutrition, and activity deserve discussion alongside laboratory results. NICE recommends weighing weekly for the first 6 weeks of antipsychotic treatment, then at 12 weeks, 1 year, and annually; early changes can support a timely conversation about treatment options rather than blame about willpower.
HbA1c of 6.5% equals 48 mmol/mol and is a diabetes diagnostic threshold, usually requiring confirmation when there are no clear symptoms. Our 高血糖の警告サイン explains why thirst, frequent urination, weight loss, or acute illness can change urgency; this threshold says nothing about the severity of psychosis.
Some antipsychotics raise prolactin, which can affect sexual function, menstruation, fertility, or other aspects of health. A result 2 times the laboratory upper limit needs interpretation with symptoms, medicines, sampling conditions, and sometimes repeat testing; our mildly elevated prolactin guide explains why one result should not trigger unsupervised medication changes.
Smoking changes can alter clozapine exposure, because combustion products—not nicotine alone—affect its metabolism. A hypothetical person stopping cigarettes during a 1-week admission needs the prescribing team's attention; diet and supplements also deserve review, but no meal plan, vitamin panel, or supplement regimen has been established as a substitute for schizophrenia treatment.
研究論文と検査結果の解釈の限界
The research references below distinguish schizophrenia guidance from supporting laboratory education. The 2 Zenodo guides explain serum proteins and immune tests; they are not schizophrenia diagnostic studies, and their DOIs do not establish peer review, psychiatric screening accuracy, or evidence that these tests should be ordered for early behavioral changes.
KantestiはAIの検査結果解釈サービス。 that explains reported measurements rather than diagnosing psychiatric disorders. Our 技術的・臨床的監督 describes the scope of our methodology; performance on laboratory interpretation is not evidence of accuracy for schizophrenia assessment, and those are 2 separate validation questions.
Serum albumin, globulins, and the A/G ratio reflect broad physiological processes, not a schizophrenia signature. Our eGFRの記事 provides context for that laboratory family; a hypothetical A/G ratio of 0.9 must be interpreted against its laboratory interval and clinical setting, not converted into a psychiatric risk score.
Complement and ANA testing answer targeted immune questions, and indiscriminate testing can produce findings unrelated to the presenting symptoms. Our 補体とANAのガイド explains those limits; an isolated ANA titer of 1:80 does not establish an autoimmune explanation for psychosis or justify immune treatment without supporting clinical evidence.
Kantesti's role is to help readers understand accompanying reports while keeping diagnosis and urgent care with qualified clinicians. For a first episode—or a change after 5 stable years—bring the symptom timeline and original results to assessment; the NICE, WHO, and APA references below support the clinical discussion, while the repository publications support narrower laboratory education.
よくある質問
統合失調症の初期症状にはどのようなものがありますか？
統合失調症の初期兆候として、引きこもり、機能の低下、異常な知覚、疑い深さ、思考や睡眠の変化などが考えられますが、こうした所見だけでは統合失調症の診断には不十分です。生活の複数の領域にわたって2つ以上の問題が重なる場合は、評価を受けることが特に有用かもしれませんが、これは診断基準ではありません。新たに声が聞こえる、通常とは異なる信念を強く抱く、または著しい機能低下がある場合は、速やかに臨床評価を受けてください。症状が数か月続くのを待ったり、血液検査の結果が出るのを待ったりせず、助けを求めてください。
幻聴がなくても統合失調症になることはありますか？
統合失調症の人が、必ずしも幻聴を経験するとは限りません。幻聴は、すべての症例において必須ではないためです。DSM-5-TRでは、活動期に特徴的な症状が少なくとも2つ認められることが求められ、そのうち少なくとも1つは妄想、幻覚、まとまりのない会話である必要があります。また、一定の持続期間と機能に関する基準も満たさなければなりません。そのため、幻聴がなくても、妄想やまとまりのない会話が顕著な場合があります。さらに、臨床家は、ほかの精神疾患、物質関連の要因、医学的要因による可能性も評価する必要があります。
血液検査で統合失調症を診断できますか？
統合失調症を診断または否定できる一般的な血液検査はなく、その目的で検証された一般的なバイオマーカーの基準値は0です。血液検査は、医学的な要因を調べたり、薬の安全性をモニタリングしたりするために行われることがありますが、これらは別の臨床的な問いです。たとえば、病歴から甲状腺の問題やビタミンB12欠乏症が疑われる場合は、検査が適切なことがあります。検査結果が正常でも、幻覚や妄想が続くこと、または機能が低下することを放置してよいわけではありません。
意欲低下や社会的引きこもりは統合失調症の兆候ですか？
Low motivation and social withdrawal can occur among the negative symptoms of schizophrenia, but they also occur with depression, sleep problems, medicines, stress, and other conditions. Clinicians commonly describe 5 negative-symptom domains: reduced expression, speech, motivation, pleasure, and social engagement. The assessment considers the person's baseline, associated symptoms, and alternative causes rather than counting behaviors on a checklist. New or persistent changes affecting daily life deserve assessment without assuming schizophrenia.
統合失調症と診断されるには、症状がどれくらいの期間続く必要がありますか？
必要な期間は、診断の枠組みと症状の全体像によって異なります。DSM-5-TRでは通常、少なくとも6か月間にわたる持続的な障害が求められ、そのうち活動期は通常少なくとも1か月続く必要があります。ただし、治療が奏功した場合はそれより短くてもかまいません。ICD-11では、追加の診断要件を満たしたうえで、特徴的な症状が少なくとも1か月間、ほとんどの時間に認められることが求められます。これらの期間は診断の指針であり、受診のタイミングを示すものではありません。初回の精神病エピソードが疑われる場合は、速やかに評価を受けてください。
統合失調症の可能性がある人は、どのような場合に救急医療を受けるべきですか？
差し迫った自傷行為、本人が実行するおそれのある危険な命令、重度の混乱、反応性の低下、または基本的なニーズを満たせない状態では、緊急のケアが必要です。英国では差し迫った危険がある場合は999または112に、米国では緊急時は911に、危機支援を求める場合は988に電話してください。突然の神経症状、筋強剛を伴う発熱、出産後に現れた新たな精神病症状についても、緊急の医学的評価が必要です。差し迫った危険がなくても、新たな精神病症状が現れた場合は、速やかに医療従事者または地域の危機対応サービスに連絡してください。
