Dementia – Diagnosis and Treatment
Diagnosis
Tests of Memory and Thinking Skills
Doctors ask special questions and give tasks to check a person’s memory, thinking, and language abilities. These tests, like the Mini-Mental State Examination (MMSE), help spot issues with short-term memory, problem-solving, or attention.
The results can show what type of dementia someone may have, such as Alzheimer’s disease or vascular dementia.
Specialized Nerve and Brain Checks
A healthcare provider checks reflexes, balance, speech, and movement during a neurological exam. This helps spot brain or nervous system problems.
Vision, touch, or coordination issues may point to certain types of dementia, like frontotemporal or Lewy body dementia.
Imaging and Brain Scans
Doctors use imaging tests like MRI, CT, and PET scans to take pictures of the brain. These scans can show strokes, tumors, or other brain problems.
MRI or CT scans highlight changes linked to Alzheimer’s or vascular dementia. PET scans display brain activity patterns and help spot amyloid or tau proteins found in Alzheimer’s disease.
Sometimes, doctors use SPECT scans or a lumbar puncture for more information.
Medical and Blood Tests
Blood tests help doctors find out if other health issues are causing symptoms. Low vitamin B12, thyroid problems, infections, or toxins might cause memory loss or confusion.
Doctors may order tests like glucose, erythrocyte sedimentation rate, or a toxicology screen. Sometimes, they check spinal fluid for signs of infection or conditions like Creutzfeldt-Jakob disease or HIV-associated dementia.
Mental Health Assessment
A psychiatric evaluation checks for mood or mental health conditions like depression or anxiety. These conditions can look like dementia or make symptoms worse.
A psychiatrist helps decide if depression or another mental health issue is causing or adding to cognitive decline.
Treatment
Medicines That Help With Symptoms
Doctors use medicine to help with some symptoms of dementia, but these do not cure the disease. Different types of drugs manage memory problems and other challenges linked to dementia.
The main medicines are cholinesterase inhibitors, memantine, and some newer options.
Cholinesterase Inhibitors Table
| Medication Name | Main Use | Key Side Effects |
|---|---|---|
| Donepezil | Improves memory and thinking | Nausea, vomiting, diarrhea, trouble sleeping, slow heartbeat |
| Rivastigmine | Improves memory and function | Upset stomach, vomiting, weight loss |
| Galantamine | For memory issues | Loss of appetite, upset stomach, tiredness, dizziness |
Cholinesterase inhibitors help brain cells communicate by raising certain chemical levels involved with memory and judgment. People with Alzheimer’s, Lewy body dementia, Parkinson’s disease dementia, or vascular dementia may take these medicines for symptoms.
Sometimes, these drugs cause stomach problems like nausea, vomiting, or diarrhea. Some people feel faint, have trouble sleeping, or notice a slower heartbeat.
Memantine is another medicine doctors may prescribe. It helps control how glutamate, a brain messenger, works. Doctors sometimes use memantine along with a cholinesterase inhibitor. Dizziness is the most common side effect.
Doctors may also prescribe other medicines for symptoms like depression, sleep problems, hallucinations, shakiness, or agitation.
Newer Medications for Early Alzheimer’s Disease Table
| Medication Name | How It’s Given | Common Side Effects | Special Precautions |
|---|---|---|---|
| Lecanemab | IV infusion every 2 weeks | Fever, nausea, shortness of breath, dizziness | Brain swelling or bleeding risk, requires brain scans and gene testing |
| Donanemab | IV infusion every 4 weeks | Headache, flu-like symptoms, nausea | Risk of allergic reactions, swelling, bleeding, genetic risk checked |
Lecanemab and donanemab are newer medicines for people with early Alzheimer’s or mild memory problems. These drugs help slow down the decline in thinking and functioning.
Doctors give these medicines by intravenous (IV) infusions at a hospital or clinic. They lower the buildup of amyloid plaques in the brain, which are linked to Alzheimer’s.
People taking these medicines may need regular brain scans to check for side effects like swelling or bleeding in the brain. These risks can be higher in people with a gene called APOE e4, so genetic testing may be needed before starting.
People on blood thinners or with other risk factors should talk with their healthcare team. Patients, families, and healthcare professionals should discuss the benefits and risks before starting these newer treatments.
Therapies and Supportive Approaches
Medicine is not the only way to manage dementia. Therapies and changes in daily routines can help someone live more safely and comfortably.
List of Helpful Therapies
Occupational Therapy: Occupational therapists teach safer ways to do daily activities and help make the home safer. They show families how to prepare for later stages of dementia and help the person avoid accidents like falls.
Creating a Safer Living Environment: Reducing noise and clutter makes it easier for someone with dementia to pay attention and feel less overwhelmed. Keeping sharp or dangerous objects out of reach helps prevent accidents. Some households use monitoring systems or alarms to know if someone wanders.
Simplifying Everyday Tasks: Dividing big jobs into small, easy steps may help reduce confusion and frustration. Focusing on what the person can do, rather than mistakes, builds confidence. Keeping a regular schedule with set routines makes the day more predictable and often lowers anxiety.
Therapy Table
| Therapy Type | Main Goal | Examples of Changes |
|---|---|---|
| Occupational Therapy | Improve safety and coping skills. | Teach new ways to do tasks, remove hazards, give support. |
| Environmental Adjustment | Make surroundings less confusing. | Remove clutter, hide keys or knives, use alarms. |
| Task Simplification | Help focus on what can be done. | Break down complex chores, use checklists, set routines. |
Therapies depend on the needs and abilities of the person with dementia. Care plans are often personalized.
Working with healthcare providers and family members helps find the best mix of therapies and supports.
Everyday Approaches and Helpful Habits
Making positive changes at home supports people living with dementia and their caregivers. Simple adjustments make daily life easier and help manage symptoms.
Communication, physical health, and routines all play key roles in well-being.
Communication Tips
When speaking with someone with dementia, keep eye contact and use clear, short sentences. Wait for a response without rushing.
Share one idea at a time and use gestures, like pointing or showing objects, to add clarity and reduce confusion.
Staying Active
Physical activity benefits both body and mind. Walking, stretching, or light exercises improve balance, strength, and heart health.
Exercise may also ease restlessness and help maintain thinking skills. These effects increase with a balanced diet and careful management of heart health risks.
Activities for Engagement
Daily activities the person enjoys help keep their mind active and provide a sense of accomplishment. Examples include gardening, painting, singing, simple cooking, or dancing.
Doing these activities together can strengthen connections between caregivers and loved ones.
Daily Structure and Sleep
Setting a regular daily routine, especially for bedtime, can reduce confusion and anxiety in the evening. Calm surroundings before sleep work best.
Avoid caffeine and limit naps during the day to make nighttime rest easier.
Staying Organized
A large, easy-to-read calendar posted in a visible spot can remind loved ones about daily events, appointments, and medication times.
Planning Ahead
Early discussions about care wishes and legal matters help families prepare for changes. Creating a plan while the person can still take part allows them to share their wishes.
Support groups and experts can help guide these planning steps.
| Tip | What to Try |
|---|---|
| Communication | Eye contact, simple sentences, gestures |
| Physical Activity | Walking, stretching, balance exercises |
| Favorite Activities | Gardening, painting, dancing, singing |
| Routine & Sleep | Calm evenings, avoid caffeine, steady routine |
| Organization | Visible calendar, reminders |
| Future Planning | Early conversations, legal and care planning |
Healthy habits, both physical and social, along with a nutritious diet, help address symptoms and maintain independence as much as possible.
Natural and Complementary Treatments
Additional Supportive Activities
Some people try supportive therapies to help manage symptoms and improve well-being. Music activities can bring calm and lower stress.
