The Human immunodeficiency virus or HIV/AIDS is the causative agent of several health conditions such as acquired immune deficiency syndrome or AIDS, and is also responsible for causing cva problems in people. However, in mild and uncomplicated cases of HIV andAIDS, cva symptoms can be quite misleading or nonexistent. Studies have shown that up to 80 percent of people with a positive HIV test but negative results on clinical examination may still have cva. This figure is much higher than the proportion of people tested who actually have the condition, indicating the necessity for cva screening in even the slightest of cases.
Cva symptoms in patients with a history of stroke are often similar to those of other stroke-impaired patients. Patients with a history of stroke may experience headache, fatigue, shortness of breath, nausea, and muscle weakness. Some patients may experience more serious or lethal CVA symptoms such as seizures and unconsciousness. When these symptoms occur, immediate medical attention is needed. Even if the initial diagnosis of stroke is incorrect, patients with a history of stroke should undergo a cerebrovascular study to determine if there is any chance of developing a stroke due to CVA.

Because so many people with a history of stroke suffer from cognitive problems, they usually have poorer motor coordination than normal. However, when the patient experiences problems with movement, they may not necessarily appear disabled. In fact, some patients with CVA or stroke may have great movement potential. Movement impairment can arise from brainstem lesions that decrease oxygenation or from increased blood pressure within brain tissue itself.
In some studies, stroke patients have demonstrated increased risk of developing an auto-immune disease called polymyalgia rheumatica (PRM), which commonly attacks the spinal cord, the lungs, the heart, and the skin. Autosomal dominant polymyalgia rheumatica (ADP) can cause inflammation of blood vessels and organs, leading to a decreased oxygenation and damaging muscles and joints. A diagnosis of CVA combined with polymyalgia rheumatica can then indicate a high possibility of developing ADP. Because stroke survivors can also have CVA, stroke survivors must be carefully screened for both conditions.
While many patients with CVA and stroke share some symptoms, some do not. One common sign of CVA is ataxia (lack of coordination). In addition, some patients who have had a history of myocardial infarction (heart attack) or unstable angina (angina caused by blood flow irregularities) also have been found to have abnormal blood flow. Myocardial infarction is characterized by blood clots that deposit in the coronary arteries, which are branches of the coronary nervous system. Patients with acute myocardial infarction can be diagnosed with either EKG or resting electrocardiograph.
On the other hand, patients with a history of hypoxia (low levels of oxygen in the brain) are more likely to have ongoing problems with blood flow. Blood clots are known to deposit in the cerebrospinal fluid, a transparent sac filled with myelin that surrounds the brain and spinal cord. Studies indicate that poor blood circulation is a risk factor for many diseases, including CVA, atherosclerosis (hardening of the arteries), stroke, Alzheimer’s disease, macular degeneration and spinal cord injury.
