Implications of medication on cognition
Medicines may cause a number of unintentional effects on a person’s cognition e.g. memory, thoughts and behaviour (see below). These effects may become apparent as soon as a new medication is started or a dose is changed, or may occur gradually over a period of time.
- Inability to concentrate
- Confusion
- Hallucinations
- Cognitive impairment
- Agitation
- Attention deficit
- Delirium
- Memory impairment
The effects may be due to the anticholinergic and/or sedative effects of these medications. Other potential adverse effects of these medications include:
Anticholinergic effects
- Dry mouth
- Urinary retention
- Constipation
- Irregular heart rate
- Blurred vision
Sedative effects
- Feeling sleepier/increased lethargy
- Slurred speech
- Dizziness, unsteadiness
If you have ANY concerns regarding possible adverse effects of a resident's medication, request a medication review.
Both anticholinergic and sedative medications are strongly associated with an increased risk of falls.
