In 40 seconds

Sundowning — agitation, confusion, anxiety appearing in late afternoon and evening — affects up to 20% of people with Alzheimer's and is one of the hardest dementia symptoms for caregivers to manage. Causes are multifactorial: circadian disruption, fatigue, sensory overload, hunger. PEMF therapy may support nervous system regulation and circadian alignment, particularly when used in mid-afternoon as preventative care. Patient-reported support is consistent.

Quick facts

How PEMF may help

Bright morning light, structured days, evening calming routines, and reduced caffeine all help with sundowning. PEMF provides nervous-system support that complements behavioural strategies.

Practical use

Mid-afternoon 30-minute session 2-3 times per week. Combined with bright light therapy in the morning and evening environment optimisation (reduced noise, calm lighting, familiar routines).

Contraindications

Standard PEMF contraindications: pacemakers, defibrillators, cochlear implants, insulin pumps, electronic implants; active malignancy without specialist clearance; pregnancy (over the abdomen); active infection; epilepsy without GP clearance.

Frequently asked questions

Will PEMF stop sundowning?

Don't expect elimination. Reduction in severity and frequency is realistic for some patients.

Mid-afternoon timing — why?

Acts preventatively before symptoms peak. Same logic as some sundowning medications.
