Izlena Syndrome

For the patient - a nonspecific cerebrovascular accident in the form of brain dysfunction with significant impairment of cognitive functions in the absence of other signs of coronary artery disease and arterial hypertension [1,2].

For a doctor, the diagnosis of “islena syndrome” means not only an acute transient cerebral disorder with retrograde amnesia, but also, in the case of progression of the condition, a cerebral vascular disease (transient cerebrovascular accident, dyscirculatory encephalopathy, ischemic stroke), which can be considered as a transient cognitive disorder or an analogue vascular dementia.

Since the cause of dyscirculatory encephalopathy in patients over 60 years of age in 80% of cases is atherosclerosis, in at least half of the cases of strokes there is also the presence of chronic high blood pressure or heart rhythm disturbances, and in the remaining patients low levels of lipids in the blood and coagulopathy are determined, it is advisable to consider diagnosis of “coronary heart disease”, if the doctor insists on this in the presence of this disease and the patient has any symptoms that emphasize them. When confirming the diagnosis of “progressive vascular dementia”, the causes of cerebral hemodynamic disturbances and forms of vascular dementia should be differentiated as accurately as possible. In cases where organic cerebral pathology (including inflammatory diseases of the brain) is detected, the diagnosis of “vascular dementia” should be established if it is of non-traumatic origin.
