1. Anatomy & Physiology
Diseases

2. Nervous System- Normal

3. Brain Activity

4. Brain Activity

5. Brain Activity

6. Cerebral Palsy Disturbance in voluntary muscle action
Caused by brain damage (birth injury, infections)
S&S = exaggerated reflexes, tense muscles, seizures, speech impairment
Tx = No cure: muscle relaxants, physical therapy, anti seizure meds

7. CVA (Stroke) Known as cerebrovascular accident
Caused by bleeding artery
S&S = weakness/ paralysis on 1 side, aphasia, difficulty swallowing
Tx = Therapy (speech, physical)

8. Stroke

9. Dementia Loss of mental function
Causes include stroke, head injury, alcohol/drug abuse, loss of nerve cells
S&S = forgetful, change in personality / mood
Tx = No cure; treat symptoms

10. Alzheimer’s Most common type of dementia
Caused by family Hx, aluminum, obesity, & increasing age
S&S = memory loss, asking same questions, repeating same story, forgetting simple tasks, getting lost in familiar places
Tx = No cure; meds to slow disease

11. Alzheimer’s

12. Alzheimer’s

13. Meningitis Inflammation of the meningitis
Caused by bacteria, virus, chemicals (lead)
S&S = high fever, headache, back/neck pain, stiff neck, N/V, delirium (late sign)
Tx = antibiotics, pain med, anti seizure med

14. Parkinson’s Disease Chronic, progressive disease
Degeneration of brain cells
S&S = tremors, stiffness, muscular rigidity, shuffling gait (late sign), loss of facial expression (late sign)
Tx = No cure; treat symptoms

15. Parkinson’s Disease

16. Autism Range of complex neurodevelopment disorders
Evident by social impairments, difficulty communicating, & repetitive behavior
Range from mild (Asperger’s) to severe (autistic disorder)

17. S&S = impaired social interaction fail to respond to their name
unable to understand emotional cues
repetitive movements

18. Cues for autism No single words by 16 mths (just noise)
No response to name
Poor eye contact (no interaction)
Lack of physical touch
Inability to make friends
Inability to converse with others
Absent imaginative play
Intense focus on certain objects
Inflexible with change of a routine

19. Causes (Theories) Genetic Disruption of brain development in utero
Enviromental
