Anatomy & Physiology Diseases

Nervous System- Normal

Brain Activity

Brain Activity

Brain Activity

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

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

Stroke

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

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

Alzheimer’s

Alzheimer’s

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

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

Parkinson’s Disease

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

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

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

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