Detailed information about psychotic episodes, hallucinations, delusions, and early intervention.
Anhedonia in schizophrenia isn't quite the same as the anhedonia of depression. Recent research distinguishes the loss of anticipatory pleasure from the loss of in-the-moment pleasure.
PsychosisBrief psychotic disorder involves sudden psychotic symptoms that resolve within a month. Most people recover fully — but the episode still deserves serious attention.
DelusionsCapgras syndrome is the rare but striking belief that a loved one has been replaced by an identical-looking impostor. It bridges psychiatry and neurology and offers a fascinating window into how the brain constructs familiarity.
Negative symptomsFlat affect is the reduction in outward expression of emotion — facial expression, vocal tone, gesture. The inner emotional life often remains intact, which makes the symptom particularly easy to misread.
Rare presentationsCycloid psychosis describes brief, intense psychotic episodes that recover fully between attacks. The label is European and historical, but the clinical picture is recognisable worldwide.
Thought disorderDerailment, sometimes called loose associations, is when ideas slip off track within a single sentence — one of the core features of formal thought disorder.
DelusionsSomatic delusions centre on the body — its shape, its insides, or what is supposedly inhabiting it. They are often highly distressing and frequently misdiagnosed.
SymptomsAlogia is the negative symptom that quietly affects conversation — fewer words, less elaboration, longer pauses. It is rarely about not having anything to say.
HallucinationsOlfactory hallucinations — phantom smells with no source — are an uncommon but real symptom in schizophrenia, and they have a long differential diagnosis worth taking seriously.
HallucinationsSmelling something that nobody else can smell is unsettling. In most cases the cause is neurological or ENT-related, but olfactory hallucinations can also occur in schizophrenia.
PsychosisSchizoaffective disorder sits in the territory between schizophrenia and bipolar or depressive illness. The diagnosis is precise — and the treatment approach reflects both halves.
Rare presentationsKurt Schneider's first-rank symptoms once defined schizophrenia almost on their own. Modern diagnostic systems have stepped back from that idea — but the symptoms themselves still matter.
PsychosisA psychotic episode is a period when a person's brain produces experiences that aren't shared by the people around them. Understanding it from the inside changes how you respond.
DelusionsErotomanic delusions — the firm belief that another person, often someone unattainable, is secretly in love with you — are uncommon but cause real distress on both sides.
SymptomsAvolition is the absence of the internal push that normally gets people moving. It's a real neurological symptom, not a character flaw — and there are things that help.
Negative symptomsAttention deficits are one of the most common cognitive symptoms of schizophrenia — and one of the strongest predictors of how someone will function day to day.
HallucinationsTasting something that isn't there is the rarest type of hallucination. Causes range from epilepsy to medication side effects, with schizophrenia accounting for a small minority.
Thought disorderNeologisms are newly invented words or familiar words used in idiosyncratic ways. They are a less common but distinctive feature of formal thought disorder.
HallucinationsTouch hallucinations — feeling pressure, crawling, heat, or being touched without a real source — are uncommon but distressing, with several possible causes worth distinguishing.
DelusionsErotomania, also called de Clérambault syndrome, is a delusion that another person — frequently a stranger or public figure — is secretly in love with the patient. It is rare but can drive serious behaviour.
Rare presentationsSimple schizophrenia described slow, insidious negative symptoms without dramatic psychosis. DSM dropped it; ICD-10 kept it; ICD-11 has now retired it too. The clinical picture remains.
PsychosisSchizophreniform disorder is the diagnostic label for psychosis lasting one to six months. It often, but not always, becomes schizophrenia.
DelusionsDelusions of reference are the eerie experience of feeling that ordinary events — a song lyric, a stranger's glance — carry hidden personal meaning meant just for you.
SymptomsFlat affect is reduced outward expression of emotion — but research shows the inner emotional experience is often largely intact. The disconnect is in expression, not in feeling.
DifferentialThree psychotic diagnoses, three time frames. The DSM uses the duration of symptoms to distinguish them — and treatment changes as the diagnosis evolves.
Thought disorderThought blocking is the sudden, abrupt interruption of a train of thought. The speaker stops mid-sentence and often cannot pick the thread back up.
HallucinationsPhantom tastes — bitter, metallic, foul — are an uncommon but recognised hallucination in schizophrenia, often appearing alongside olfactory experiences and a long differential diagnosis.
HallucinationsHearing music that nobody else can hear is more common than people think — and far more often a sign of hearing loss than psychiatric illness.
DelusionsThought broadcasting, insertion, and withdrawal are among the most disorienting experiences in psychosis — the felt sense that the boundary of one's own mind has been breached.
SymptomsThe DSM-5 removed the paranoid subtype of schizophrenia in 2013. The clinical pattern it described still occurs in many people — and understanding it helps treatment.
