What is schizophrenia?

opleiding binaire opties Schizophrenia is an interesting disorder, characterized by cognition disturbances and behavioral and emotional concerns.1 Some patients suffer from hallucinations, paranoia, and delusions.1 These symptoms can lead to cognitive deficits and social avoidance.1 Patients experience reduced brain volume in the prefrontal cortex and temporal lobes, which most likely cause these deficits.1 Schizophrenia is also  commonly associated with dopamine system dysfunction, and dopamine plays a large part in the reward- and pleasure-seeking symptoms.1 When an illicit drug is used, the function of the dopamine transporters are blocked, resulting in an increase in dopamine, or feelings of pleasure.1

Schizophrenia & Substance Use: Self-Medication or Vulnerability?

Tadalafil på nätet säkert SchizophreniaThe link between schizophrenia and substance abuse has been explained best by two main, and different, hypotheses: the self-medication hypothesis (SMH) and the addiction vulnerability hypothesis (AVH).1 The SMH hypothesis states that drugs of abuse relieve some psychological suffering that a patient is undergoing, while the AVH hypothesis states that schizophrenia increases a person’s vulnerability to drug reward and reinforcement.1 SMH states that drug addiction is a reaction to schizophrenia, as it relieves depression, blunted affect, and neurocognitive deficits.1 However, as SMH focuses mainly on self-report measures, many researchers question the hypothesis’ validity.1 After conducting a study on the effects of smoking nicotine in schizophrenics, the hypothesis also states that smoking actually improves visuospatial working memory (VSWM).1 However, medicines can help increase VSWM without the use of nicotine and its harmful effects on the body.1 If the SMH hypothesis was supported, drug use would not be a problem for people with schizophrenia.1
