Differentiate between ischemic stroke, hemorrhagic stroke, and transient ischemic attack. Identify the common risk factors, signs and symptoms of stroke. Describe the importance of imaging/labs to confirm stroke. Explain the different etiologies/pathophysiology of ischemic stroke. List the most common types of hemorrhagic stroke.
Understand the Problem
The questions are inquiring about stroke, specifically regarding different types of strokes, risk factors, the role of imaging and laboratory tests in diagnosis, the pathophysiology of ischemic stroke, and classifications of hemorrhagic stroke. These are fundamental concepts in medical science, particularly in neurology.
Answer
Ischemic strokes - blocked arteries; Hemorrhagic strokes - blood vessel rupture; TIAs - temporary blockages. Risk factors: high BP, diabetes, smoking. CT/MRI important for diagnosis. Ischemic types: thrombotic, embolic; Hemorrhagic types: intracerebral, subarachnoid.
Ischemic strokes are due to blocked arteries, hemorrhagic strokes occur when a blood vessel ruptures, and TIAs are temporary blockages with no lasting damage. Common risk factors include high blood pressure, diabetes, and smoking. Imaging like CT or MRI is vital for diagnosis. Ischemic strokes can be thrombotic or embolic, while hemorrhagic can be intracerebral or subarachnoid.

Ischemic strokes can be thrombotic or embolic, while hemorrhagic can be intracerebral or subarachnoid.
More Information
Ischemic strokes are often classified into embolic, where a clot travels to the brain, or thrombotic, where a clot forms locally. Hemorrhagic strokes are categorized into intracerebral, bleeding within the brain, and subarachnoid, bleeding in the area between the brain and tissues covering it.
Tips
Not distinguishing between stroke types can lead to incorrect treatment. Ensure proper imaging is conducted to confirm the type of stroke.
