Study Notes
Alzheimer’s disease
- Most common form of dementia
- Cause: Idiopathic (unknown)
- Common in elderly (average onset at 50 years old)
- Risk factors: advancing age, family history, women
- Characterized by gradual onset of recent memory loss (anterograde amnesia)
- Hallmark manifestation: neurofibrillary tangles in the brain, high levels of Tau proteins in nerve tissue
- Symptoms: anterograde amnesia, agnosia, apraxia, aphasia, ataxia, cognitive changes, aggressive behavior, apathy, wandering behavior, muscle atrophy, incontinence
- Diagnosis: confirmed via autopsy
- Management: medications like Donepezil to slow progression, reminiscence therapy for mental stimulation, focus on safety (well-lit environment, avoid clutter)
- Complications: pneumonia, death from secondary complications
Aphasia
- Absence of the ability to communicate properly and coherently
- Broca’s Aphasia (Expressive Aphasia): difficulty in speaking and writing, confusion, slurring and stuttering
- Wernicke’s Aphasia (Receptive Aphasia): difficulty in understanding spoken and written language, confusion, limited ability to comprehend instructions
- Global or Mixed Aphasia: Both Broca's and Wernicke's Aphasia
Guillain-Barré Syndrome (GBS)
- Temporary neurologic deficit from an autoimmune response, characterized by polyradiculoneuropathy
- Mechanism: Autoimmune response that attacks nerves and spinal tissue, damaging myelin sheath and axons
- Types of GBS:
- Acute Inflammatory Demyelinating Polyneuropathy (AIDP): most common variety, characterized by ascending paralysis, motor deficits (weakness, atrophy), and sensory deficits
- Acute Motor Axonal Neuropathy (AMAN): most common in East Asia, retains sensation, associated with Campylobacter jejuni infection
- Miller-Fisher Syndrome (MFS): associated with Zika virus infection, mainly affects eye muscles with ataxia and areflexia
- Symptoms: temporary loss of function such as movement, bladder and bowel elimination, respiratory failure
- Progression: self-limiting, complete recovery expected within weeks, as long as the client survives
- Diagnosis: CT, MRI, PET scan, CSF analysis to confirm inflammation
- Risk factors: recent viral illnesses (influenza, mononucleosis, COVID-19), bacterial infections (Campylobacter jejuni), vaccine components (influenza, HiB)
Parkinson’s Disease
- Progressive degeneration of the substantia nigra
- Cause: idiopathic, though risk factors include advancing age, viral illness (especially in elders), family history, toxins and pesticides
- Characterized by the presence and progression of 5 Cardinal Signs:
- Unintentional tremors: resting tremors, “pill rolling” tremors
- Rigidity: stiffness, unilateral or bilateral
- Bradykinesia: slow movement with unsteady gait, shuffling gait
- Postural changes: hunched back, shuffling gait, generalized stiffness
- Loss of automatic movements: inability to blink, frown, grimace, or swing arms while walking, resulting in masked face
- Management: focus on safety, mild to moderate exercise, soft diet, respiratory function, preventing atrophy
- Medical management: medication like Dopar/Levodopa (most effective)
- Complications: pneumonia, death from secondary complications
