Can subarachnoid haemorrhage be traumatic? Traumatic subarachnoid haemorrhage (SAH) can be produced by acceleration/deceleration forces without any impact to the head. Traumatic SAH is usually present on the convexity of the brain without causing mass effect. These happen due to rupture of small blood vessels. They are often associated with underlying brain contusion but can also occur in isolation. The accumulation of blood in subarachnoid space can happen as a result of post-mortem artefact resulting from decomposition. Massive SAH at the base of brain are usually caused by rupture of vertebral or basilar aneurysm (a natural cause). 55. What is Stroke? What are its causes and whether it can cause death? In India, nearly one- ifth of patients with irst ever strokes admitted to hospitals are aged <40 years. In young adults ischemic stroke remains the commonest type of stroke. Overall, ischemic strokes account for about 80% of all strokes in India. Hypertension, electrocardiogram (ECG) abnormality, heart disease of any type, diabetes, smoking, and alcohol were associated with stroke. Cerebral venous thrombosis and rheumatic heart disease are the leading causes of stroke among youngs in India. Tubercular meningitis leading to arteritis or autoimmune angitis is also important stroke risk factors in young. The most common symptom of a stroke is sudden weakness or numbness of the face, arm, or leg, most often on one side of the body, occurring in 90% of the strokes. A severe stroke can even cause sudden death. 56. Whether bleeding in brain can happen naturally? Spontaneous non-traumatic bleeding in the brain substance occurs most commonly in middle to late adult life. Most are caused by rupture of small brain matter blood vessel; of which hypertension remains the most common underlying cause. Individuals with coronary heart disease, angina, or who have had a heart attack due to atherosclerosis, have more than twice the risk of stroke than those who haven't.
