FBC, U+E, LFT, TSH, Urine drug test, HIV, Syphillis, B12, anti-NDMA receptors (encephalitis) if neurological features.
What is the prognosis in acute psychosis?
4/5 symptoms resolve. Most (4/5) will have a relapse in the next 5 years. The longer symptoms go untreated, the more likely it is that people will have persisting positive and negative symptoms. Early referral is important for this reason.

Personality disorders, dissociative disorder, PTSD, Anxiety disorders, Autism.
Name some second generation antipsychotics

Fewer extrapyramidal side effects- (dystonia, akathisia, Parkinsonian features and tardive dyskinesia)
What is the aim of treatment in psychosis?
Treat acute psychotic symptoms, prevent relapse, manage chronic symptoms, reduce risk of worsening associated symptoms and loss of functioning, Severe untreated disease can result in self- harm/neglect/harm to others
If two second generation antipsychotics fail what is tried next and what is the risk of this?
Clozapine- requires careful monitoring because of risk of agranulocytosis.
How long should antipsychotics be continued?
At least two years as there is a risk of relapse if stopped prior to this
