Movements: Alzheimer's disease affects mainly memory and other cognitive functions. Parkinson's disease affects movements, either by tremor or by rigidity. It does not affect cognitive functions in the early stages.

Parkinson's: movement disorder causing tremors at rest, stiffness, gait impairments, but specific dementia affecting memory retrieval, distance judgement, organizational skills, fluctuating responsivity, florid hallucinations. Alzheimers: late may affect gait, but main issue is loss of ability to learn new information, getting lost & disoriented, reversed sleep, behavior disruption, no tremors.
