Stroke
Stroke is a medical emergency that occurs when the blood supply to your brain is interrupted or reduced, thereby preventing brain tissue from getting oxygen and nutrients. Without blood, your brain cells begin to die. This can cause serious symptoms, paralysis, disability, and even death.
There are 2 main types of stroke;
• Ischemic stroke: An ischemic stroke occurs when a blood clot keeps blood from flowing to your brain. The blood clot is often due to atherosclerosis, which is a buildup of fatty deposits on the inner lining of a blood vessel
• Hemorrhagic stroke: A hemorrhagic stroke results when a blood vessel in your brain ruptures or breaks, spilling blood into the surrounding tissues.
There is also Transient ischaemic attack, also called mini-stroke. In this case, the blood clot and symptoms last for a short period of time.
Signs and Symptoms
• Trouble speaking and understanding what others are saying
• Paralysis or numbness of the face, arm or leg
• Headache: A sudden, severe headache, which may be accompanied by vomiting, dizziness or altered consciousness, may indicate that you're having a stroke.
• Problems seeing in one or both eyes
• Trouble walking
The National Stroke Association recommends the FAST method to help identify the warning signs of a stroke:
Face: When you smile, does one side of your face droop?
Arms: When you raise both arms, does one arm drift down?
Speech: Is your speech slurred? Are you having trouble talking?
Time: If you experience any of these symptoms, call for help immediately.
Risk factors
Many factors can increase your stroke risk. Potentially treatable stroke risk factors include:
Lifestyle risk factors
• Being overweight or obese
• Physical inactivity
• Heavy or binge drinking
• Use of illegal drugs such as co***ne and methamphetamine
Medical risk factors
• High blood pressure
• Cigarette smoking or second-hand smoke exposure
• High cholesterol
• Diabetes
Complications
• Paralysis or loss of muscle movement
• Difficulty talking or swallowing
• Memory loss or thinking difficulties
• Emotional problems
• Pain
Diagnosis
Things will move quickly once you get to the hospital, as your emergency team tries to determine what type of stroke you're having. That means you'll have a CT scan, MRI, or other imaging tests soon after your arrival. The team also need to rule out other possible causes of your symptoms, such as a brain tumor or a drug reaction.
Treatment
Emergency treatment for stroke depends on whether you're having an ischaemic stroke or a stroke that involves bleeding into your brain. A wide range of treatment techniques and approaches from different philosophical backgrounds are utilized in Stroke Rehabilitation.
Physiotherapy management
Evidence has shown that task-oriented exercise training program is effective to restore patient's function including mobility, balance, gait, and for strengthening the affected lower limb to improve functional independence. Furthermore, physiotherapy facilitates upper limb training through constraint-induced movement therapy to improve the ability to perform functional upper limb activities. In addition, physiotherapy helps reduce the associated pain and spasticity, and may recommend a walking aid to prevent falls.
