Symptoms of memory loss include:
- Difficulty paying attention and concentrating
- Difficulty organizing thoughts or actions
- Difficulty deciding what to do next
- Difficulty speaking
- Difficulty understanding speech
Causes and Risk Factors
Patients at risk of experiencing a transient ischemic attack are at a higher risk of developing memory loss due to a TIA. Risk factors for experiencing a TIA include:
- Narrowing of the arteries, usually caused by atherosclerosis. This is when fatty material builds up and hardens on an artery wall. This material can break off and get lodged in smaller blood vessels in the brain.
- Cerebral artery stenosis
- Spasms in the walls of the arteries
- High blood pressure
- A lack of oxygen in the blood flowing to the brain, which can occur when a person is severely anemic, has carbon monoxide poisoning or has leukemia or polycythemia, a condition that produces abnormal blood cells and clotting
