Dementia: Clear signs, when to act and simple steps to help

Worried about forgetfulness in yourself or someone you care for? Dementia is more than memory loss. This page gives plain, useful steps: how to spot common signs, what a doctor will check, basic treatment options, and everyday care tips you can use right away.

Recognize early signs

Not every slip of memory is dementia. Watch for changes that affect daily life: repeating questions, getting lost in familiar places, trouble handling money or bills, sudden personality or mood shifts, or trouble finding words. Also notice problems with planning, following conversations, or seeing things differently (like misjudging distances).

There are different types of dementia. Alzheimer’s is the most common, but vascular dementia follows strokes or poor blood flow. Lewy body dementia often brings visual hallucinations and sleep problems. Frontotemporal dementia affects personality and language first. Type matters because the course and treatments can differ.

When to see a doctor and what to expect

If changes are steady or they interfere with daily tasks, call your doctor. Don’t wait for a crisis. The evaluation usually includes a medical history, short cognitive tests, basic blood work, and sometimes brain imaging like MRI or CT. These steps help rule out treatable causes such as vitamin deficiencies, thyroid problems, infections, or medication effects.

Telling the doctor specific examples helps a lot. Note when symptoms started, how they changed day-to-day, any falls or fainting, and a list of medicines. Bring a family member if possible—they often notice things the person misses.

Basic treatment options

There’s no cure for most dementias, but some drugs can slow symptoms for a time. Cholinesterase inhibitors (donepezil, rivastigmine, galantamine) help thinking and memory in some people. Memantine may help in moderate to severe stages. Side effects and benefits vary—discuss risks with a clinician. Treat other problems too: depression, sleep issues, pain, and urinary infections can worsen thinking.

Practical care tips you can use today

Make routines simple: consistent times for meals, meds, and sleep reduce confusion. Label drawers and doors. Cut tasks into one-step actions and use clear, calm language. Remove trip hazards and install good lighting to prevent falls. For wandering, consider a GPS-enabled ID or door alarms. Keep social contact and light activity—short walks and familiar tasks often help mood and function.

Plan ahead: sort out legal documents, power of attorney, and care wishes while the person can still decide. Caregiving is hard—use support groups, ask family to share tasks, and take breaks. Respite care and community programs can give you breathing room.
