Study Notes
- PD (Parkinson's Disease) is a disorder affecting the basal ganglia, particularly the dopaminergic tract, leading to neuronal loss in the substantia nigra pars compacta.
- PD diagnosis relies on medical history and neurological examination, as there are no specific blood or laboratory tests.
- PD treatment includes dopamine agonists, enzyme inhibitors, Amantadine, Anticholinergic drugs, and deep brain stimulation.
- AD (Alzheimer's Disease) is a neurodegenerative disorder characterized by amyloid-β accumulation, making up 60-80% of all dementias.
- AD affects memory (amnesia), communication (aphasia), physical functioning (apraxia), and understanding information from the senses (agnosia).
- AD diagnosis relies on signs and symptoms of mental decline, with routine laboratory tests showing no abnormality and CT brain revealing cerebral atrophy.
- MND (Motor Neuron Diseases) is a group of neurological conditions affecting motor neurons in the brain and spinal cord.
- MND damages upper and lower motor neurons, leading to muscle weakness and eventually wasting.
- Causes of MND are unknown, with ongoing research focusing on viruses, toxins, genetics, inflammation, and nerve growth factors.
- MND can be hereditary and presents with various symptoms, such as muscle weakness, speech difficulties, and respiratory changes.
- MND diagnosis involves ruling out other conditions through blood tests, urine tests, MRI brain scans, nerve conduction studies, electromyography, and muscle biopsy.
- MND has no cure, but symptoms can be managed with medications, including muscle relaxants, pain relievers, and medications to help with breathing.
