61 year old patient with alcohol abuse suffers a stroke
Anatomy of brain
Cerebrum
largest part of the brain
composed of right/left hemispheres
Four regions/lobes
frontal lobe
solves complex task
undergo voluntary movements of body parts
form complete sentences
personality trait
parietal lobe
general sensation and feeling
temporal lobe
auditory processing
cerebellum
located under the cerebrum
coordinate muscle movements
maintain posture and balance
brain stem
controls the flow messages b/w the brain and the rest of the body
direct cause of stroke
sudden interruption of blood supply to the brain
ischemic stroke
abrupt blockage of an artery
hemorrhagic
bleeding into brain tissue when a blood vessel bursts
immediate effect of stroke on the brain
part of brain that helps with speaking
aphasia/dysparsia
weakness in the muscles that help with speech
mental faculties or his ability to play the piano
For some stroke survivors, rehabilitation will be an ongoing process to maintain and refine skills and could involve working with specialists for months or years after the stroke.
factors if conditions worsens over time
high blood pressure
diabetes
high blood cholesterol levels
Factors if conditions improve over time
speaking ability will improve
taking control of blood pressure
physical movements may improve
If patient continues to drink heavily
increase risk of developing another stroke
abstain from alcohol completely
Stroke
Symptoms & Outcomes
depends primarily on the location
extent of brain tissue damage
Sudden interruption in the blood supply of the brain
White matter
found in the deeper tissues of the brain
contains nerve fibers
protect nerve fibers from injury
affects learning and brain function
Grey matter
distinguished from white matter
contains numerous cell bodies
few myelinated axon
Ventricle System
lateral ventricles
located within the hemispheres of the cerebrum
3rd Ventricle
between the right and the left thalamus
Fourth Ventricle
it receives CSF from the third ventricle via the cerebral aqueduct.
communicating cavities within the brain
Effects of alcohol on the brain
blocks chemical signals between brain cells
slurred speech
poor memory
impulsive behavior
Regions of diencephalon
Thalamus
make up most of the mass diencephon
relay station for almost all sensory info
Hypothalamus
located above the brain stem
made up of a collection of nuceli
Subthalamus
made of tissues from the midbrain
home to the subthalamic nucleus and zona incerta
Epithalamus
Primarily of the pineal gland and the habenulae
secretes the hormone melatonin
Effects of alcohol on the brain
blocks chemical signal between brain cells
impulsive behavior
slurred speech
poor memory
slowed reflexes
reasons for specific symptoms
stroke affected left side of brain
dysarthia
motor speech problem
affects of alcohol abuse
triggers atrail fibrillation
a type of irregular heartbeat
increase risk of stroke by 5xs
