Do antipsychotics change the brain permanently?
Meyer-Lindberg himself published a study last year showing that antipsychotics cause quickly reversible changes in brain volume that do not reflect permanent loss of neurons (see “Antipsychotic deflates the brain”). The idea that decreased brain volumes are necessarily bad is also controversial.
How long do you stay on antipsychotics?
Some people need to keep taking it long term. If you have only had one psychotic episode and you have recovered well, you would normally need to continue treatment for 1–2 years after recovery.

Does antipsychotics cause memory loss?
Rather than positive effects, antipsychotics may have adverse effects on cognition. First-generation antipsychotics have been shown to impair procedural learning and memory, especially at high doses [7, 8].
Does psychosis damage the brain?
The impacts of untreated psychosis
First-episode psychosis (FEP) can result in a loss of up to 1% of total brain volume and up to 3% of cortical gray matter. When FEP goes untreated, approximately 10 to 12 cc of brain tissue—basically a tablespoon of cells and myelin—could be permanently damaged.
Do antipsychotics block dopamine?
Generally speaking, antipsychotic medications work by blocking a specific subtype of the dopamine receptor, referred to as the D2 receptor. Older antipsychotics, known as conventional antipsychotics, block the D2 receptor and improve positive symptoms.
Do antipsychotics do more harm than good?
Lately, however, some studies have suggested that antipsychotics may do more harm than good, especially in the long-term. Some researchers have raised concerns over the toxic effects of these medications, suggesting that patients may only benefit from the medication in the short-term.
Which antipsychotic has less side effects?
Aripiprazole is similar in effectiveness to risperidone and somewhat better than ziprasidone. Aripiprazole had less side- effects than olanzapine and risperidone (such as weight gain, sleepiness, heart problems, shaking and increased cholesterol levels).
What is the antidote for antipsychotics?
There is no specific antidote for the atypical antipsychotics. Treatment is symptomatic and supportive. Patients should be monitored for CNS depression, cardiac toxicity, including hypotension and ECG abnormalities, and the possibility of seizures. In general, patients should be observed for 4-6 hours after overdose.
