Implication of Parkinson's Disease Flashcards
what are the abnormal motor features of PD?
slowness of movement, rigidity, resting
tremor, postural instability, forward flexed posture, freezing
phenomenon
what are the non-motor features of PD?
dementia, sleep disorders,
emotional behaviours, loss of appetite, anosmia, reduced gastric
motility
what are the chracteristics of PD?
- loss of dopamine producitng cells in mid-brain neurons
- loss of neuromelanin
*accumumation of Lewy-bodies
*death of astrocytes
*increase number of reective microglia
why do dopamine cells die?
*dendritic complexity due to high energy demand = depletion of ATP to feed the Na+/K+ pump
*mitochondrial toxins and deficits
what are the significance of neuroimmune system?
*distinct from perepheral immune system
*protects neurones fron pathogens visa inflammation (phogocytosis)
* composed primarily of glial cells
what are the current treatments for PD?
- dopamine replacement
- dopamine agonists
- monoamine oxidase-B inhibitor
- deep brain stimulation
- transcaranial magnetic stimulation
- neutrophic agents like GDNF
what are the complications of dopamine replacements
little to no effect on non-motor features of PD and short acting
what are the non-dopaminergic agents for motor impairment?
*anti-cholinergics
*glutamate antagonists
* muscle relaxants (diazepam)
what are the non-dopaminergic agents for non-motor impairment
*Dementia (rivastigmine)
* Depression (SSRIs)
* Insomina (zolpidem)
what are the future treatments for PD?
cell replacement/ stem cell replacement
what treatment can be done for non-motor complication in PD?
Promoting endogenous repair via rejuvenation of new neurone formation in the hippocampus
to promote memory function.
