The nervous system can develop several types of disorders, which can affect the clients you care for. The disorders can cause different problems depending on their cause and the area of the nervous system involved
There are two main types of stroke: an ischemic stroke, which occurs when there’s a blockage of an artery, and a hemorrhagic stroke, which occurs when an artery in the brain leaks into the brain tissue.
Another mechanism for ischemic stroke is an embolism. This happens when a blood clot breaks off from an atherosclerotic plaque from an artery outside the brain, breaks loose, and travels to the brain where it gets lodged in a cerebral artery.
Factors that can increase the client's risk for having a thrombotic or embolic stroke include anything associated with atherosclerosis, like smoking, hypertension, or high blood pressure; diabetes; and a diet high in saturated fat.
Now, sometimes a small clot can block a cerebral artery for a short period of time before dissolving, restoring normal blood flow.
Both stroke and seizures are medical conditions that can affect the nervous system. A stroke occurs when a part of the brain loses its blood supply. There are two main types of stroke: an ischemic stroke, which occurs when there's a blockage of an artery, typically from a thrombus or embolus; and a hemorrhagic stroke, which occurs when an artery in the brain ruptures and leaks blood into the brain.
A stroke may result in permanent disability, like hemiplegia or aphasia. Acute care focuses on the early reestablishment of blood flow and supportive measures, while long-term care may include speech, physical, and occupational therapy.
On the other hand, seizures are sudden, abnormal electrical discharges in the brain that can cause changes in movement, behavior, and consciousness. These can be focal seizures, meaning that they affect one small area in one brain hemisphere, or generalized seizures, which affect both hemispheres and include tonic-clonic and absence seizures.
