Statistically, out of all patients with schizophrenia, "10%...commit suicide. Depressed patients with schizophrenia are at a particularly high risk for suicide the first few months after diagnosis and after hospital discharge." Risk factors increasing the chance of suicide are, from highest to lowest, previous depressive orders, previous suicide attempts, drug abuse, and several other factors. Surprisingly, the suicide risk actually decreased with the presence of hallucinations. The ICD-10 Classification of Mental and Behavioural Disorders officially recognizes suicide as being a prominent aspect of post-schizophrenic depression. Because of this drastic increase in suicide, it can be difficult to study post-schizophrenic depression as many of those affected take their own lives. Treatment
For a number of years, scholars debated amongst themselves whether or not antipsychotic drugs had a tendency to increase depression or simply help the patient manage their mental illness. However, conclusive evidence points to antipsychotic drugs actually helping patients with their depression while simultaneously assisting in the suppression of schizophrenic episodes. Specifically risperidone, olanzapine, quetiapine, fluphenazine, haloperidol, and L-sulpiride have done the best in drug trials pertaining to people with schizophrenia. Along with antipsychotic drugs, post-schizophrenic patients may receive antidepressants to actively treat the depression. Drugs are certainly not the only answer, though. At the base of both depression and schizophrenia, social withdrawal is a shared symptom between the two. People with schizophrenia require a strong support system to be healthy, just as is the case with the rest the human population.
Muscle atrophy is the loss of skeletal muscle mass. It can be caused by immobility, aging, malnutrition, medications, or a wide range of injuries or diseases that impact the musculoskeletal or nervous system. Muscle atrophy leads to muscle weakness and causes disability. Disuse causes rapid muscle atrophy and often occurs during injury or illness that requires immobilization of a limb or bed rest. Depending on the duration of disuse and the health of the individual, this may be fully reversed with activity. Malnutrition first causes fat loss but may progress to muscle atrophy in prolonged starvation and can be reversed with nutritional therapy. In contrast, cachexia is a wasting syndrome caused by an underlying disease such as cancer that causes dramatic muscle atrophy and cannot be completely reversed with nutritional therapy. Sarcopenia is age-related muscle atrophy and can be slowed by exercise. Finally, diseases of the muscles such as muscular dystrophy or myopathies can cause atrophy, as well as damage to the nervous system such as in spinal cord injury or stroke. Thus, muscle atrophy is usually a finding (sign or symptom) in a disease rather than being a disease by itself. However, some syndromes of muscular atrophy are classified as disease spectrums or disease entities rather than as clinical syndromes alone, such as the various spinal muscular atrophies. Muscle atrophy results from an imbalance between protein synthesis and protein degradation, although the mechanisms are incompletely understood and are variable depending on the cause.
