Stroke

Stroke occurs when there’s a blockage in the blood supply to the brain it happens when a blood vessel in the brain ruptures and bleeds. Furthermore, oxygen supply to the brain ceases leading to brain damage.Stroke

Types of Strokes

There are three types of strokes with sub-types                    Ischemic Stroke                        Transient Ischemic Attack                                                               Hemorrhagic Stroke   

Due to arteries being blocked or narrowed, ischemic stroke can also occur when too much plaque clogs blood vessel.

Ischemic stroke                                                                              1.Thrombotic- when a blood clot forms in one of the arteries supplying blood to the brain.                                                                            2. Embolic- when a blood clot or other debris forms in another part of the body go towards the brain.

Transient Ischemic Attack                                                              Is a temporary blockage period of symptoms similar to those you’d have in a stroke also know as mini stroke usually last 5 minutes.

Hemorrhagic stroke                                                                          When there is bleeding in the brain -.Blood vessel in your brain balloons up and bursts or a weakened one leaks.

  1. Intracerebral hemorrhagic– when the tissues surrounding the brain fill with blood after an artery bursts.
  2. Subarachnoid hemorrhagic– when bleeding in the area between the brain and the tissues that cover it.

Symptoms

Generally stroke occurs without warning

  • Trouble walking, including dizziness and lack of co-ordination
  • Numbness or inability to move parts of the face, arm or leg
  • Confusion, headache, possibly with vomiting
  • Trouble with speaking and understanding
  • Vision problems

Risk factors

BackgroundsStroke

Sex                                          Both women and men can have strokes, they’re more common in women than in men in all age groups.                                    Age                                         The older you are, the more likely you are to have a stroke.                                                            Family history                                                                                   Stroke risk is higher in some families because of genetic health.            Race and ethnicity                                                                           Caucasians, Asian Americans, and Hispanics are less likely than African-Americans, Alaska  Natives, and American Indians.

Blood tests                                  MRI and CT scan                        EKG- Electrocardiogram              Cerebral angiogram                    Carotid ultrasound                      Echocardiogram

Recovering from a strokeStroke

Rehabilitation offers hope of increased function and return to the level of activity that they had prior to the stroke. However it depends upon the underlying health of the patient and severity.

Rehabilitation may take weeks or months depending on the patients health conditions.
