CONFLICT OF INTEREST DISCLOSURE
I have no potential conflict of interest to report
Falls and dementia
- 60 % of people with dementia fall annually
- Few studies have investigated falls among participants with
dementia
- To investigate how community-dwelling
persons with Alzheimer’s disease (AD) fall
– When? Why? How? Consequences?
- FINALEX study was 1-year RCT exercise
intervention study among AD patients
– Home-based/group-based exercise (N=129) 2x/wk – Controls: normal community care (N=65)
Aim and introduction
Methods
- Participants in the FINALEX study:
– Alzheimer Disease – An ability to walk independently with/without mobility aid – Sign of frailty:
- ≥1 fall / previous 12 months OR
- unintentional weight loss OR
- slow gait speed
Pitkala et al. JAMA Intern Med. 2013 ;173:894-901.
- Participants’ (N=194) falls were followed up for one year by diaries kept by
their spouses.
- Groups formed for participants with 0 (N=103), 1 (N=34) and ≥2 (N=57)
falls
- We investigated various features and risk factors behind the falls.
Methods
Results: Falls: when, why, consequences
- Altogether 355 falls:
- Half of them at midday, rest equally during morning, evening, and
night time
- The most common reasons for falls were stumbling (N=61),
dizziness (N=37), and weakness of legs (N=18)
- In most cases, the spouses were unable to state the reason for
falling
- Of 355 falls, 123 led to injuries, 50 to emergency department visits,
and 13 to fractures

Strenghts
- Participants had confirmed diagnosis of
Alzheimer’s Disease
- Diary is the best method to accurately record falls
- Prospective and detailed follow-up
- The participants were motivated caucasians
living at home with their spouses - generalization?
- The number of participants was small
- Intervention reduced the number of falls
– the number of falls is underestimate of real life – modifying falls also?
Limitations
- Alzheimer’s Disease patients have increased fall risk
- Polypharmacy, anticholinergic drugs, psychotropics, and
- pioids increase the fall risk – confounding by indication?
- Individuals with MMSE ~10 are at greatest risk
- COPD, diabetes, osteoarthritis increase fall risk
- Good physical functioning protects against falls
- In this study hypertension and antihypertensive medication
were protective factors –mechanism?
