RISK FACTORS FOR NEUROLOGIC IMPAIRMENT
- Hypertension*
- Chronic atrial fibrillation and flutter
- Obesity*
- Sedentary life-style*
- Smoking tobacco products*
- Stress*
- Increased levels of serum cholesterol, lipoproteins, and triglycerides*
- Use of oral contraceptives in high-risk women*
- Family history of diabetes mellitus, CVD, hypertension, increased serum cholesterol levels
- Congenital cerebrovascular anomalies
- Modifiable risk factors - Health Promotion Opportunities
PHYSICAL EXAMINATION ASSESSMENT
- Mental status: LOC, speech, cognitive, orientation, memory function, emotional status
- Glasgow coma scale
T/F: Level of consciousness is the most sensitive indicator of neurologic deterioration
- True
ALERTNESS LOC EXAMINATION ASSESSMENT
- Speak to patient in a normal tone of voice
- Alert patient opens eyes, looks at you, responds fully and appropriately to stimuli
LETHARGY LOC EXAMINATION ASSESSMENT
- Speak to the patient in a loud voice
- Call the patient’s name or ask “how are you?”
- Patient appears drowsy but opens eyes and looks at you
- Responds to questions then falls asleep
OBTUNDATION LOC EXAMINATION ASSESSMENT
- Shake patient gently
- Patient opens eyes and looks at you
- Responds slowly and somewhat confused
- Alertness and interest are decreased
