Hemoglobin S changes flexible red blood cells into rigid, sickle-shaped cells. Methods We studied a Swedish kindred with ischemic stroke and intracerebral hemorrhage, tremor, dysautonomia, and mild cognitive decline. A hemorrhagic stroke is caused by a blood vessel that bursts and bleeds into the brain. Brain cells can be damaged or die within minutes, causing symptoms in the parts of the body they control. A stroke is a medical emergency. It can cause brain damage, long-term disability and death. Host genetic factors, moreover, may modify the response to these environmental challenges and are responsible for developmental vascular instability. The genetic abnormality can range from minuscule to major -- from a discrete mutation in a single base in the DNA of a single gene to a gross chromosomal abnormality involving the addition or subtraction of an entire chromosome or set of chromosomes. In most cases, a stroke is caused by a blood clot that blocks blood flow to the brain. The extent of the impact of this silent disease on public health remains unclear, but … GWAS is a new method to study common genetic variation across the entire human genome, designed to identify genetic associations with observable traits. 1) Huntington’s Disease.
