Arteries can calcify during the years and important brain areas start lacking oxygen. Therefore some processes which are controlled by the affected areas fail – like the coordination of walking.
The term experts use for that is subcortical arteriosclerotic encephalopathy (SAE). A usual symptom for SAE patients is that the walking problems are accompanied by psychological variances, and they also often have problems when they urinate. If the context is perceived in time, the progress of the disease can be clogged, says professor Johannes Jörg, neurologist at the Helios Clinic in Wuppertal, who is hosting the MEDICA symposium “New Neurological Diagnostics and Therapies Concerning the Elderly”.
Critical for a better blood flow within the brain is mainly the blood pressure. The formerly spreaded approach that an increased blood pressure is necessary for older people for an adequate brain performance is no longer valid. Having reached mature age, blood pressure should be under 140 to 90 mmHg, with diabetes or lipometabolism dysfunction even lower, recommends Jörg.
A bad blood circulation in the brain can also have other reasons: it can also result from an increased brain pressure, which narrows or even blocks veins and arteries. These patients have too much brain liquid, which is not reabsorbed adequately anymore. If the liquid accumulation gets too high, the brain pressure increases and nerve pathways will supplied with less blood. Typical for these patients is an intermittent walking trouble: Sometimes moving legs works well, sometimes it doesn’t. The removal of brain liquid often brings relief to these patients – and immediately they are able to walk properly again.
