What mental diseases are inherited
So it is laid by nature – we all during the life of something sick and not once. ARI, chickenpox, flu, sore throat – this is a small part of what each of us had been ill. But in the world there are diseases that are inherited, like a terrible curse. Their occurrence is difficult to predict. A child whose parents suffered from a hereditary disease does not necessarily have to be born sick, but he will always have a high risk of developing this disease.
To date, there are 3,000 genetic diseases that are inherited. Fortunately, among them the main part consists of diseases, the risk of which in a child is only 3-5%. Genetic diseases that occur in virtually every generation always have a suppressive gene. In this case, the carrier of the sick gene can be one of the parents, or both. Just in the first case, the risk of developing a genetic disease in a child will be 2 times less.
The most common inherited diseases are diabetes, hypertension, psoriasis, color blindness, congenital deafness, epilepsy, and schizophrenia. Among them, the most dangerous are mental illnesses that negatively affect the person’s adequate behavior. The mentally ill loses the ability to think reasonably and communicate normally with people.
Neurological hereditary diseases can occur in people of all ages, but some of them do not appear immediately after birth, but 20-40 years later. Such dangerous disorders of the nervous system include:
1. Parkinson’s Disease. Most often, this disease affects people after 50-60 years, then progresses steadily. Its main features include poor coordination of movements, trembling hands, chin and legs, slow walking. In addition, with this disease, there is a lack of emotion, a slowdown in thinking and attention, a deterioration of speech and the development of depression. As the disease progresses, memory and intellect deteriorate, complete immobility occurs when the patient is confined to a wheelchair or bed.
2. Alzheimer’s disease. This disease begins to manifest itself before the age of 65, but it is difficult to diagnose in the early stages of development due to the non-specific clinical picture. The first signs of Alzheimer’s disease are forgetfulness, confusion and inability to do things that were previously easy. Later, dementia, unreasonable irritability and aggression develop, with time speech and loss of all vital functions of the body are disturbed.
3. Amyotrophic lateral sclerosis. The first manifestations of this disease, which is usually called ALS, can be felt by patients after 40 years. ALS is an incurable progressive disease of the central nervous system, in which paralysis and muscle atrophy occur due to degenerative lesions of the upper and lower motor neurons of the brain. As a result of all these processes, a fatal outcome occurs within a few years, due to severe pneumonia or failure of the respiratory muscles.
