Cerebrovascular diseases are one of the most urgent and priority problems of modern medicine. With an increase in life expectancy, there is a significant increase in cerebrovascular pathology, in particular, chronic cerebral ischemia, with a clear correlation between dysfunction of the cardiovascular and other visceral systems of the body and deterioration in the state and functioning of the central nervous system (1,2).

Autonomic dysfunction syndrome is currently considered as a comorbid pathology of chronic cerebral ischemia that accompanies it as it develops. With increasing age, the patient has a gradation of autonomic dysfunction. Changes occurring in the autonomic nervous system precede subsequent neurological disorders and serve as a manifestation of maladaptive reactions (3).

Over the past 10 years, the incidence of chronic bronchopulmonary pathology has increased by 21% in relation to the total incidence, while chronic obstructive pulmonary disease is the most common pathology among respiratory diseases (1,2,3,4). Due to the body's reduced immune defenses, patients with COPD have an increased susceptibility to viral infections, including SARS-CoV-2. The prevalence of COPD is higher among patients with more severe forms of COVID-19 (5). The emergence of a new infectious agent has set the challenges for healthcare professionals related to rapid diagnosis and timely provision of medical care to this category of patients (6).

We have dedicated this article to one of the vital algae spirulina. While writing this article, we found that spirulina is one of the important products of which is used in the fields of manufacturing, pharmaceuticals, food purposes and others. And we also studied clinical studies conducted by American specialists, obesity, zinc deficiency, alcoholism, depression, aging symptoms and schizophrenia can also be associated with a deficiency of gamma-linolenic acid contained in spirulina. As a result of the collected information, we compiled a table. We studied the role in nature and in human life.
