Stroke is caused by interruption of blood supply to the brain. It can be from hemorrhage or atherosclerosis (hardening of the arteries).
Symptoms can vary, depending on the area of the brain involved and the extent of the infarction. Some of the common symptoms include: sudden numbness, weakness of the face, arm, or leg, especially on one side of the body. Trouble with speech, vision changes, confusion, and drooping of the face are relatively common.
It is imperative that the treatment be sought within a couple of hours of the onset of symptoms. Getting to the emergency room can be life-saving, and long-term morbidity can be spared.
Infusion of stem cells have shown promise in improving the residual symptoms, thereby improving the quality of life.
It is a chronic degenerative neurological disorder, whereby due to some triggering factors, dopamine producing cells in the brain get destroyed. Dopamine, being a neurotransmitter, is essential for the movements of the body.
The cardinal symptoms of the disease are slowness of movements, rigidity, and tremor. The disease tends to be progressive and more symptoms develop with the passage of time, including difficulty with balance and coordination and struggles with speech and swallowing.
Because of the progressive nature of the disease, it affects all spheres of life. No cure is currently available and all medications tend to alleviate some symptoms, but carry severe side effects including involuntary movements (dyskinesia).
With stem cell therapy, we hope the undifferentiated stem cells can differentiate into neural tissue and reverse some of the symptoms of this devastating disease. It has been promising.
