Stroke and its Symptoms
A stroke occurs when the blood supply to part of your brain is interrupted or reduced, depriving brain tissue of oxygen and nutrients. Within minutes, brain cells begin to die.
Patients may experience confusion as well as slurring words or have difficulty understanding speech.
Patients may develop sudden numbness, weakness or paralysis in the face, arm or leg. This often happens just on one side of the body
Patients may suddenly have blurred or blackened vision in one or both eyes, or they may see double.
A sudden, severe headache, which may be accompanied by vomiting, dizziness or altered consciousness, may indicate they are having a stroke.
Patients may stumble or experience sudden dizziness, loss of balance or loss of coordination.
Functions of the Brain
Frontal Lobe: (personality, behavior, emotions, judgment, planning, problem solving, speaking and writing, body movement, intelligence, concentration, self awareness)
Parietal Lobe: (interprets language, words, sense of touch, pain, temperature, interprets signals from vision, hearing, motor, sensory and memory, spatial and visual perception)
Occiptial Lobe: (interprets vision)
Temporal Lobe: (understanding language, memory, hearing, sequencing and organization)
Effects of 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
If heavy drinking continues over a long period of time, the brain adapts to the blocked signals by responding more dramatically to certain brain chemicals (called neurotransmitters)
Anatomy of the Brain
The cerebrum is divided into two halves: the right and left hemispheres. They are joined by a bundle of fibers called the corpus callosum that transmits messages from one side to the other. Each hemisphere controls the opposite side of the body. If a stroke occurs on the right side of the brain, your left arm or leg may be weak or paralyzed.
Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
Cerebellum: is located under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance
Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the spinal cord. It performs many automatic functions such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing
A 61 year-old male piano teacher with a long history of alcohol abuse was admitted to the hospital after
suffering a stroke
Won't be able to use his right hand and arm
Inability to speak indicates that he has lost his mental faculties
Patient is be more vulnerable to the negative effects that alcohol can have
It can worsen mood swings and depression, which are common after stroke. It can also affect memory and thinking
Alcohol makes the body dehydrated, so if the patient suffering from headaches, drinking alcohol could make them worse
Weakness, paralysis, and problems with balance or coordination
Right side weakness
Speech and language problems
