Study Notes
Neurodegenerative Diseases
- The primary obstacle in treating neurodegenerative diseases is the inability to identify a single cause or target for treatment.
- Neurodegenerative diseases are characterized by neuronal damage, which is the primary cause of the disease.
Neurotransmitters
- L-DOPA (3,4-dihydroxy-L-phenylalanine) is a precursor to norepinephrine in noradrenergic pathways.
- Dopamine is a neurotransmitter in the Nigrostriatal tract and regulates movement by inhibiting GABA-ergic and cholinergic neurons.
- Excess glutamate causes neuronal damage by excitotoxicity.
Neurodegenerative Diseases: Causes of Neuronal Damage
- Apoptosis (programmed cell death) is one of the causes of neuronal damage in neurodegenerative diseases.
Parkinson's Disease
- Parkinson's disease is characterized by damage to the substantia nigra and affects movement regulation.
- Dopamine replacement therapy, using drugs such as L-DOPA, is used to manage the symptoms of Parkinson's disease by regulating kinesis.
Key Points
- Drugs used in the management of neurodegenerative diseases typically only provide symptomatic relief because they do not address the underlying cause of the disease.
