What Are the Effects of a Brain Aneurysm?

The effects of a brain aneurysm vary a great deal from short-term to long-term deficits, according to the Brain Aneurysm Foundation. Sometimes personalities are affected when people experience changes in behavior, mood and emotions. Significant physical and cognitive losses also happen. In addition, some patients suffer strokes.

Brain aneurysms cause certain patients to lose physical skills. Some experience partial loss of vision, complete blindness or loss of peripheral vision, explains the Brain Aneurysm Foundation. The ability to speak clearly or even swallow is affected. Coordination suffers, and balancing becomes difficult. There is a general, ongoing feeling of tiredness. Thought processes that are impacted include short-term memory. Patients have trouble concentrating and sometimes have difficulty understanding and processing information. Perceptual abilities are skewed.

The level of impairment often depends on when surgery occurred. If the aneurysm was known and its removal was planned, surgery is often less complicated, notes the Brain Aneurysm Foundation. Recovery is, therefore, usually quicker than if the aneurysm ruptured unexpectedly. Thirty percent of aneurysm patients make a full recovery. Improvements take months or years, depending on the individual. Neuropsychiatrists or neuropsychologists are able to measure the level of cognitive functioning and other issues. Patients often need the assistance of speech, physical or occupational therapists to recuperate.
