Neostigmine bromide (pyridostigmine, Mestinon, Tensilon ) |
|
Myasthenia Gravis
cholinesterase inhibitor drugs / anticholinesterase meds, what do they do? |

|
Alzheimers Disease: Chemical changes in the brain related to this disease
|
abnormalities in the neurotransmitters (acetylcholine, norepinephrine, dopamine, serotonin
-high levels of beta amyloid are associated with reduced Ach which leads to a decrease in the amount of acetyltransferase in the hippocampus..this loss is major because the decrease in acetyltransferase interferes with cholinergic innervations to the cerebral cortex. this results in impaired cognition, recent memory, and the ability to acquire new memories. |
|
Alzheimers Disease:
Medications` |
Acetylcholinesterase inhibitors, such as Reminyl, Aricept, & Exelon;
