What are some important considerations for dementia?
Here's a few mnemonics that might be helpful:
Remember the reversible causes of DEMENTIA
Metabolic (hypothyroidism, order TSH!)
Emotions (screen for depression!)
Nutrition (Vit B1/B12... order B12!)
Tumor/Trauma/"Tension"-Normal Pressure Hydrocephalus
Infection (neurosyphilis, consider RPR!)
Anemia/Atherosclerosis (order CBC!)
I'm very fond of important mnemonics that help me quickly recall things at the bedside, especially if they can be easily detected and treated before it progresses into something much more permanent.
GOMERS go to ground - The Fat Man, House of God. (Elderly people have a tendency to fall.)
There's a ton of mnemonics on falling. IHATEFALLING, CATASTROPHE*... those are too long but you can google them at your leisure.
GMA MOVES is more to my liking.
Alcohol and drug use
Medical illness (PNA, MI, anemia, hyponatremia)
Environmental hazards (poor lighting, stairs, rugs, uneven floors)
Syncope, vertigo, presyncope, or disequilibrium
See my post on the Mini Mental Status Exam (ORArL 321 RWD!)
Fall Prevention checklists: Patient Handouts
 * The CATASTROPHE mnemonic is not available on the AAFP article so I've tracked it down for you.
Functional hx after a fall in the elderly
Alcohol (including w/drawal)
Tx (meds & compliance)
Affect (depression, lack of initiative)
Pain w/ mobility
