Share on Pinterest Researchers say long-term use of antipsychotic medications – particularly first-generation antipsychotics – may lead to gray matter loss in the brain. First author Dr.
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')7.
For neurological, neuropsychological, neurophysiological, and metabolic abnormalities of cerebral function, in fact, there is evidence suggesting that antipsychotic medications decrease the abnormalities and return the brain to more normal function.
Evidence of the rapidity at which antipsychotics can affect brain volume in humans was recently provided by Tost and associates. These investigators found a significant, reversible decrease in striatal volume in healthy subjects within 2 hours after they were treated intravenously with haloperidol.
Even though the majority of patients receive antipsychotics and benefit from reduction in psychotic symptoms, many patients continue to have negative symptoms, cognitive impairments, and progressive brain tissue loss.
Previous research has also shown that the use of antipsychotics may raise the risk of metabolic syndrome in patients with schizophrenia. Metabolic syndrome has, in turn, been associated with heart disease and diabetes.
Taking antipsychotics can increase your risk of developing metabolic syndrome. If you experiencing metabolic syndrome, this means you are at higher risk of developing: diabetes. stroke.
So while treatment with some antipsychotics seems to increase intelligence, others reduce symptoms without that effect. Other medications that are known to cause improved cognitive functioning had no effect when combined with those antipsychotics.
For people with schizophrenia, long-term antipsychotic use is usually accompanied by adverse effects such as weight gain, metabolic syndrome, diabetes, and ischemic heart disease, demonstrating their important role in increased mortality.
Antipsychotics are often recommended life-long for people diagnosed with schizophrenia or other serious mental illnesses because they are effective at controlling psychotic symptoms in the short term and might reduce the risk of relapse.
Tardive Dyskinesia
It is characterized by uncontrolled facial movements such as protruding tongue, chewing or sucking motions and making faces. Tardive dyskinesia is a very serious side effect of antipsychotic medications in particular, and patients taking such drugs should know what to watch for.
The researchers found that individuals with schizophrenia treated with antipsychotics demonstrated progressive loss of gray matter in the brain, compared with healthy controls.
We know that antipsychotics shrink the brain in a dose-dependent manner (4) and benzodiazepines, antidepressants and ADHD drugs also seem to cause permanent brain damage (5).
In particular, antipsychotic drugs have been linked to an increased risk of falls, diabetes and heart disease. Older adults are also more likely to be prescribed multiple medications, increasing the likelihood of negative drug interactions.
They can cause movement disorders such as twitching and restlessness, sedation and weight gain, and lead to diabetes. Because of these side effects, antipsychotic drugs are usually only used to treat severe mental illnesses such as schizophrenia or bipolar disorder.
Some people may be able to stop taking antipsychotics without problems, but others can find it very difficult. If you have been taking them for some time, it can be more difficult to come off them. This is especially if you have been taking them for one year or longer.
Clozapine and olanzapine have the safest therapeutic effect, while the side effect of neutropenia must be controlled by 3 weekly blood controls.
Consensus guidelines typically recommend continued antipsychotic medication for 1–2 years, although it has been suggested that treatment discontinuation in the form of targeted intermittent treatment (dose reduction, antipsychotic discontinuation if feasible, and immediate reintroduction if symptoms reemerge) should ...
Recently, neuropsychological findings were reported from a group of individuals with schizophrenia who had a mean estimated pre-morbid IQ of 120 [Reference MacCabe, Brébion, Reichenberg, Ganguly, McKenna and Murray21].
Of the atypical antipsychotics, risperidone is the weakest in terms of atypicality criteria.
Results: Antipsychotics, as a group, increase weight and may lead to dry mouth and bad breath, cataracts, hirsutism, acne, and voice changes; they may disturb symmetry of gait and heighten the risk for tics and spasms and incontinence, potentially undermining a person's attractiveness.
Amongst the many adverse effects of the first generation, or 'typical' antipsychotics, the most disturbing was Tardive Dyskinesia, which involves uncontrollable movements of face, hands and feet [2].
Antipsychotics can help manage your symptoms of psychosis. This can help you feel more in control of your life, particularly if you are finding the psychotic symptoms distressing. Research suggests 4 out of 5 people with severe mental illness, who take antipsychotics, find they're successful in treating their symptoms.
The long-term side effects include tardive dyskinesia (TD), a disorder characterized by involuntary movements most often affecting the mouth, lips and tongue, and sometimes the trunk or other parts of the body such as arms and legs.
