The causes of schizophrenia that underlie the development of schizophrenia, a psychiatric disorder, are complex and not clearly understood.A number of hypotheses including the dopamine hypothesis, and the glutamate hypothesis have been put forward in an attempt to explain the link between altered brain function and the symptoms and development of schizophrenia.
Schizophrenia is termed a mental illness because its causes are not completely known or understood. [120] Psychiatrists R. D. Laing , Silvano Arieti , Theodore Lidz and others have argued that the symptoms of what is called mental illness are comprehensible reactions to impossible demands that society and particularly family life place on ...
The causes of schizophrenia may include genetic and environmental factors. [7] Genetic factors include a variety of common and rare genetic variants . [ 21 ] Possible environmental factors include being raised in a city , childhood adversity, cannabis use during adolescence, infections, the age of a person's mother or father , and poor ...
The glutamate hypothesis of schizophrenia models the subset of pathologic mechanisms of schizophrenia linked to glutamatergic signaling. The hypothesis was initially based on a set of clinical, neuropathological, and, later, genetic findings pointing at a hypofunction of glutamatergic signaling via NMDA receptors .
Other causes include: trauma, sleep deprivation, some medical conditions, certain medications, and drugs such as alcohol, cannabis, hallucinogens, and stimulants. [7] One type, known as postpartum psychosis, can occur after giving birth. [8] The neurotransmitter dopamine is believed to play an important role.
It appears, therefore, that there are multiple causes for psychosis and schizophrenia, including gene mutations and anatomical lesions. Many argue that other theories concerning the cause of schizophrenia may be more reliable in some cases, such as the glutamate hypothesis , GABA hypothesis, dysconnection hypothesis, and Bayesian inference ...
The last image we have of Patrick Cagey is of his first moments as a free man. He has just walked out of a 30-day drug treatment center in Georgetown, Kentucky, dressed in gym clothes and carrying a Nike duffel bag.
Risk factors for mental illness include psychological trauma, adverse childhood experiences, genetic predisposition, and personality traits. [7] [8] Correlations between mental disorders and substance use are also found to have a two way relationship, in that substance use can lead to the development of mental disorders and having mental disorders can lead to substance use/abuse.
