Vascular Health and Brain Recovery Essentials

Proprioception is the ability to recognize joint positions, with some vascular issues involving the spinal cord leading to problems like direct connections between abnormal arteries and veins, causing venous congestion and spinal cord congestion.
Alcohol intake can increase the risk of strokes, clots, and hemorrhages, contributing to poor vessel integrity, especially in patients with aneurysms who indulge in drugs like cocaine and methamphetamines.
Drugs like cocaine and methamphetamines can damage vessels, increase blood pressure, and cause vessel hemorrhages due to their impact on vessel integrity.
Moderation in alcohol consumption is advised to avoid strokes, with recent studies suggesting that zero to two drinks per week is a safe range for non-alcoholic adults.
Concussions, common in sports like football and soccer, can lead to long-term issues like CTE, with eye tracking being a sensitive method to detect brain problems post-concussion.
MR scans may not show molecular abnormalities post-concussion, necessitating more sophisticated neurological testing like eye tracking for accurate assessment of brain recovery.
