[ROLA I WARTOŚĆ ROKOWNICZA MIKROKRWAWIEŃ MÓZGOWYCH W SCHORZENIACH NEUROLOGICZNYCH THE ROLE AND PROGNOSTIC VALUE OF CEREBRAL MICROBLEEDS IN NEUROLOGICAL DISORDERS 907].

Cerebral microbleeds (CMB) are small foci of low signal which are detected in neuroimaging. They correspond to hemosiderin and other blood breakdown products from brain vessels whose structure was affected by pathological processes. Their pathogenesis is closely related to angiopathy associated with hypertension and cerebral amyloid angiopathy. Microbleeds occur in a completely healthy population as well as in numerous neurological disorders. They are often present in people afflicted with dementia, in the course of neurodegenerative diseases and due to vascular causes. Their prevalence is also higher in people with ischemic stroke and in non-traumatic intracerebral bleeding. The presence of microbleeds is reflected in the prognosis of the patients, the presence of complications of treatment, and the occurrence of the disease entities in previously healthy people. They also affect the emotional state and quality of life of patients. We will try to summarize the current state of knowledge regarding the relationship between microbleeds and neurological disorders and present their potential predictive value.
