The Drunken Brain
BRAIN ANATOMY

-
-
Diencephalon
-
-
Epithalamus
-
Houses habenular nuclei
relay signals from the limbic system to the midbrain are involved in visceral/emotional responses to odors

Limbic System

Fornix
connect the hippocampus to the mammillary bodies of the hypothalamus, the mammillary bodies to the anterior nuclei of the thalamus and the hippocampus to the septal nuclei in the nucleus accumbens.

Alcohol on the brain
-
It blocks chemical signals between brain cells (called neurons), leading to the common immediate symptoms of intoxication, including impulsive behavior, slurred speech, poor memory, and slowed reflexes.
Short-term symptoms indicating reduced brain function include difficulty walking, blurred vision, slowed reaction time, and compromised memory.
Damage to the hippocampus region (responsible for memory creation) is severely affected by drinking and “blackouts,” leading to short-term memory loss and brain cell death.
alcohol moves through the blood-brain barrier, affecting the brain’s neurons directly.
WHAT CAUSES A STROKE?
A stroke may be caused by a blocked artery (ischemic stroke) or the leaking or bursting of a blood vessel

ALCOHOL & A STROKE
-
Drinking more than one or two drinks in a sitting can cause rapid rise in blood pressure, which in someone with very high levels of hypertension can lead to stroke.
Blood vessels damaged by high blood pressure can narrow, rupture or leak
lso cause blood clots to form in the arteries leading to your brain, blocking blood flow and potentially causing a stroke

STROKE ON THE BRAIN
-
The patient may have loss his ability to speak, but he did not lose his intelligence
He may need treatment to regain his range & motion on his right hand & arm, if there's any left
