Nervous System Disorders

Disorder of the nervous system may occur as a result of the impact on the organism of a variety of exogenous and endogenous factors that affect the metabolism, the structure and function of nerve cells.

Pathogenic effects on the nervous system may have a physical factors such as ionising radiation, electric current, noise, vibration, electromagnetic field, mechanical trauma, high and low temperature.

The function of the nervous system may be compromised by the action of different toxic substances of natural or artificial origin. Disorder of the nervous system, especially its сentral division, may be accompanied by disturbances of metabolism in the body.

The brain is very sensitive to hypoglycemia. Almost all the oxygen consumption of the brain is the oxidation of glucose. With a sharp decrease in the level of glucose in the blood there occurs a violation of brain waves, and there may be a loss of consciousness. Prolonged hypoglycemia causes irreversible damage to the brain cortex. Disorders of the nervous system are observed in the changes in the blood levels of electrolytes and hydrogen ions. Fasting, in a particular vitamin, often leads to infringement of nervous activity. Especially important in this respect are vitamins of B group.

Pathology of the nervous system may be hereditary. This is expressed immaturity of some structures of the nervous system and metabolic abnormalities in different groups of neurons. Sometimes the defeat of the nervous system in hereditary diseases may have a secondary character.

Disorders of the nervous system are possible as a result of the development of the typical pathological processes - inflammation, tumor, local violations of the circulatory system.

Nervous system depression is not the same thing as depression where you feel sad. It means slowing down of the nervous system. Nervous system depression causes things like slowed heartbeat, dulled mental ability, and slow reflexes. Some drugs and medical conditions can cause this. Sedatives are one medication that causes depression of the nervous system.

Bipolar disorder, or manic–depressive disorder, is a psychiatric diagnosis that describes a category of mood disorders defined by the presence of one or more episodes of abnormally elevated energy levels, cognition, and mood with or without one or more depressive episodes. The elevated moods are clinically referred to as mania or, if milder, hypomania. Individuals who experience manic episodes also commonly experience depressive episodes or symptoms, or a mixed state with features of both mania and depression present at the same time. These events are usually separated by periods of "normal" mood. However, in some individuals, depression and mania may rapidly alternate, which is known as rapid cycling. Extreme manic episodes can sometimes lead to psychotic symptoms such as delusions and hallucinations. Severe enough symptoms may even lead to suicide.
