Stroke: Recognition, Management, and Rehabilitation for PLAB 1
This module covers the critical aspects of stroke recognition, immediate management, and rehabilitation, focusing on knowledge essential for the PLAB 1 exam and adherence to UK guidelines.
Understanding Stroke
A stroke, or cerebrovascular accident (CVA), occurs when the blood supply to part of the brain is interrupted or reduced, preventing brain tissue from getting oxygen and nutrients. Brain cells begin to die in minutes. There are two main types of stroke:
| Stroke Type | Description | Common Causes |
|---|---|---|
| Ischemic Stroke | Caused by a blocked artery supplying blood to the brain. | Blood clots (thrombosis or embolism), atherosclerosis. |
| Hemorrhagic Stroke | Caused by a ruptured blood vessel in the brain or on its surface. | High blood pressure, aneurysms, arteriovenous malformations (AVMs). |
Recognizing Stroke: The FAST Acronym
Prompt recognition is crucial for timely intervention. The FAST acronym is a simple yet effective tool for identifying potential stroke symptoms:
FAST stands for:
- Face Drooping: Ask the person to smile. Does one side of the face droop?
- Arm Weakness: Ask the person to raise both arms. Does one arm drift downward?
- Speech Difficulty: Ask the person to repeat a simple sentence. Is their speech slurred or strange?
- Time to call 999: If you observe any of these signs, call emergency services immediately.
Other potential symptoms include sudden numbness or weakness, confusion, trouble seeing, trouble walking, dizziness, loss of balance or coordination, and severe headache with no known cause.
T stands for Time. It's critical because immediate medical attention is vital for effective stroke treatment and minimizing brain damage.
Immediate Management of Stroke
Upon suspecting a stroke, immediate action is paramount. This involves:

Key management principles include:
Rehabilitation and Long-Term Care
Stroke rehabilitation is a multidisciplinary process aimed at helping individuals regain lost function and improve their quality of life. It begins as soon as possible after the stroke and continues for months or even years.
Rehabilitation strategies are tailored to the individual's deficits and may include physiotherapy to improve mobility and balance, occupational therapy to help with daily living activities (dressing, eating), speech and language therapy for communication and swallowing difficulties, and psychological support to address emotional and cognitive changes. The goal is to maximize independence and facilitate reintegration into the community.

UK guidelines emphasize a person-centered approach, involving the patient and their family in setting goals. This includes addressing:
Physiotherapy, occupational therapy, speech and language therapy, and psychological support.
Secondary Prevention
Preventing a recurrent stroke is a critical component of long-term management. This involves addressing modifiable risk factors such as hypertension, hyperlipidemia, diabetes, atrial fibrillation, smoking, and lifestyle factors.
Adherence to prescribed medications (e.g., antiplatelets, statins, antihypertensives) and lifestyle modifications is crucial for secondary prevention.
