Drug Treated Schizophrenia, Schizoaffective and Bipolar Disorder Patients Evaluated by qEEG Absolute Spectral Power and Mean Frequency Analysis.

Objective: Research of electroencephalograph (EEG) power spectrum and mean frequency has shown inconsistent results in patients with schizophrenic, schizoaffective and bipolar disorders during medication when compared to normal subjects thus; the characterization of these parameters is an important task.

Methods: We applied quantitative EEG (qEEG) to investigate 38 control, 15 schizophrenic, 7 schizoaffective and 11 bipolar disorder subjects which remaine under the administration of psychotropic drugs (except control group). Absolute spectral power (ASP), mean frequency and hemispheric electrical asymmetry were measured by 19 derivation qEEG.

Pituitary microadenoma treated with antipsychotic drug aripiprazole.

Male patient 24 years old with a pituitary microadenoma and mental and behavioural disorders due to multiple drug use and use of other psychoactive substances (cocaine, cannabis and alcohol) were treated with haloperidol (dopamine receptor blocker) 10 mg daily. In the last control, the patient presented mammary hypertrophy; laboratory testing and brain magnetic resonance imaging (MRI) was performed, reporting the presence of a pituitary microadenoma syndrome with hormonal alteration (Prolactin levels 28.4 ng/ml).

Schizophernia and empty sella - casual or correlated?

A male patient, 44 years old, with schizophrenia which started at the age of 18. At his last follow-up visit, laboratory tests and brain magnetic resonance imaging (MRI) were performed, revealing the presence of a sellar arachnoidocele. To our knowledge, there is only one similar case report of a set of male monozygotic triplets with schizophrenia and empty sella syndrome.
