Abstract
Cerebral amyloid angiopathy (CAA) is one form of disease of the small vessels of the brain and can cause frequent cerebral hemorrhages as well as other types of stroke. The aim of the study was to analyze the static and dynamic balance of the body and changes in the tension of selected muscles of the cervical spine in patients with CAA after stroke, depending on visual control or its absence, compared to healthy volunteers. Eight stroke patients and eight healthy subjects were examined. The functional Unterberger test and the Biodex SD platform were used to test the dynamic equilibrium, on which the static equilibrium was also assessed. Muscle tension was tested with the Luna EMG device. In static tests, the LC muscle (longus colli) was significantly more active with and without visual control (p = 0.016; p = 0.002), and in dynamic tests, significantly higher results for MOS (p = 0.046) were noted. The comparison of the groups led to the conclusion that the more functional deficits, the more difficult it is to keep balance, also with eye control.

Cerebral amyloid angiopathy (CAA) is one of the forms of diseases of the small vessels of the brain
We present a group of stroke patients diagnosed with CAA
The analysis showed that stroke patients scored higher for anterior, posteriori, medial and lateral for both eyes closed and eyes open
Summary
Cerebral amyloid angiopathy (CAA) is one of the forms of diseases of the small vessels of the brain. It causes the deposition of β-amyloid protein in the wall of arterioles, capillaries and venous vessels located in the cerebral cortex and the soft dura. Similar to Alzheimer’s disease, it is a degenerative disease of the group of diseases called amyloidopathy It is a disease of old age and is the second most common (after atherosclerosis) cause of recurrent cerebral haemorrhages [4,5,6,7,8,9,10,11,12,13,14,15,16,17,18]. CAA is characterized by a variable course and a chronically progressive disease process [19,20]
