Neurological Disease Flashcards
What is a Cerebrovascular Accident (CVA)?
Stroke
Caused by interrupted circulation for the brain
Can lead to ischemia and brain tissue damage
What is an Occlusive / Thrombotic Stroke?
The most common type of stroke
Caused by a blockage in a blood vessel. Patients often have a past history of vessel disease
Whats a common HX for patients with a Occlusive / Thrombotic stroke?
-Atherosclerosis
-Brain tumor
-Valvular heart disease
-A Fib
What is a Hemorrhagic Stroke?
brain bleed caused by a rupture blood vessel
Rapid development
What are some risk factors for stroke?
-Age
-Chronic alcohol consumption
-High cholesterol
-HX of TIA
-Cardiac disease / Hypertension
-Cocaine use
-Smoking
-Arrhythmias
-Oral contraceptive use
-Diabetes
SS of Stroke
Facial Droop
Bilateral Arm weakness
Bilateral Grip weakness
Dizziness
Severe Headache
Nausea / Vommiting
Dysphagia (Swallowing Dificulties)
Asphagia (Language Difficulty)
Seizure
Decreased LOC
Unequal Pupils
Hypertension
What is a transient ischemic attack (TIA)?
“mini stroke”
Interuption of O2 to the brain, through either a blockage or bleed.
Unlike strokes, TIAs must be self resolved within 24 hours, or they are considered CVAs
SS of a TIA
Facial droop
Bilateral arm weakness
Bilateral grip weakness
Dizziness
headache
Arrhythmias
Seizure
Unequal pupils
Altered LOC
Hypertension
What is a seizure?
Occurs when neurons fire sudden and erratically
Common causes of seizures:
Abscess
AIDs
Alcohol
Birth defect
Brain infection (meningitis)
Trauma
Diabetes
Fever
Incorrect medical dosing
Drugs
Stroke / TIA
Tumor
Uremia (toxin build up due to failing kidneys)
what are the phases in a Grand Mal / Tonic - Clonic seizure
- Aura: varies with each patient, could include: Seeing a spot, muscle twitch or tasting a taste
- Loss of conciousness
- Tonic: full body rigidity
4.Hypertonic phase: Arched back and rigidity
- Clonic: Rhythmic conraction of major muscle groups
- Post seizure: Muslces relax, eyes may be rolled back
- Postictal: Reset period of the brain. Could take hours for pt to regain post seizure conciousness
What is status elipticus?
A seizure that lasts longer than 4-5 minutes
2 or more seizures occur without the return of conciousness
What is syncope?
Fainting
Sudden temporary loss of consciousness. The brain uses glucose at a high rate and has no ability to store it, leading to a 3-5 second interruption of blood flow
SS of syncope
Fear
Stress
Pain
Spinning room
Sudden rush of V-tach after syncope
BP drops
What is Alzheimer disease?
Progressive, Irreversible brain disorder.
Most common form is dementia
