Alzheimer's Disease

Gambaran keseluruhan

Alzheimer's disease is a brain condition that slowly damages memory, thinking, and the ability to do everyday tasks. It is the most common cause of dementia (a general term for memory loss and other thinking problems that are severe enough to interfere with daily life).

Alzheimer's disease is very common, especially in people over 65. About 1 in 14 people over 65 and 1 in 6 people over 80 have dementia, and Alzheimer's is the most common type.

Alzheimer's mainly affects older adults, but it can also affect younger people (early-onset Alzheimer's). It affects both men and women, though women are slightly more likely to develop it.

Gejala

• Increased confusion in the evening (sundowning)

Punca

Punca utama

• A build-up of abnormal proteins in the brain, called amyloid plaques and tau tangles, which damage and kill brain cells
• Genetics: certain genes, like the APOE ε4 gene, increase risk but don't guarantee the disease
• Age-related changes in the brain, including inflammation and reduced energy production

Faktor risiko

• Getting older (the main risk factor)
• Having a family history of Alzheimer's or other dementias
• Having certain genes, especially APOE ε4
• Head injuries in the past
• Conditions that affect heart and blood vessels, like high blood pressure, diabetes, high cholesterol, and obesity
• Smoking, excessive alcohol use, and lack of physical activity
• Social isolation and lack of mental stimulation

Bila perlu berjumpa doktor

Jumpa doktor dengan segera jika:

• Seek same-day medical help if the person has a sudden change in thinking or behavior that comes on in hours or days (could be an infection or other illness)
• If the person is having trouble speaking, seeing, or moving (possible stroke)

Buat temujanji rutin jika:

• If you or a family member notices memory or thinking problems that are getting worse
• If these problems are affecting daily life, even in small ways
• If you have concerns about your own memory or thinking abilities

Diagnosis

There is no single test for Alzheimer's disease. A doctor will take a detailed history, talk with you and a family member, and perform tests to rule out other causes of memory loss. The diagnosis is made based on the pattern of symptoms and the results of several assessments.

Ujian yang mungkin dilakukan

• Medical history and physical exam
• Memory and thinking tests (cognitive assessments)
• Blood and urine tests to check for other health conditions
• Brain imaging, such as MRI or CT scan, to look for changes in the brain
• Sometimes a PET scan or lumbar puncture (spinal tap) to detect amyloid or tau proteins

Apa yang diharapkan semasa temujanji anda

The diagnostic process can take several weeks or months. It often involves a specialist like a neurologist or a memory clinic. You will discuss your symptoms, have cognitive tests, and may need scans. The doctor will explain the results and what they mean.

Rawatan

Treatment for Alzheimer's disease focuses on managing symptoms, supporting quality of life, and planning for the future. A team of healthcare professionals, including doctors, nurses, occupational therapists, and social workers, can help. Medications can help with memory and thinking for some people, but they do not stop the disease from progressing.

Penjagaan diri di rumah

• Keep a routine for meals, sleep, and daily activities
• Stay physically active with activities like walking, dancing, or gardening (as able)
• Do mentally stimulating activities, such as puzzles, reading, or learning new skills
• Stay socially connected with family, friends, or community groups
• Use memory aids like calendars, notes, and labeled containers
• Plan for safety at home, such as removing trip hazards and improving lighting

Rawatan perubatan

Medications may be prescribed to help with memory, confusion, and behavior problems. These include drugs that increase levels of brain chemicals involved in memory and communication, and others that can help with mood or agitation. All medications should be discussed with a doctor. Non-drug approaches, like cognitive stimulation therapy and lifestyle changes, are also very important.

Bila pembedahan dipertimbangkan?

Surgery is not a treatment for Alzheimer's disease itself. However, people with Alzheimer's may need surgery for other health problems. It is important to discuss anesthesia and recovery plans with the medical team.

Hidup dengan keadaan ini

Living with Alzheimer's means adjusting to changes in memory and thinking. Many people can still enjoy life for years with support. Creating a calm and predictable environment, using reminders, and focusing on abilities rather than losses can help. It is important to plan for legal, financial, and care decisions while the person can still participate.

Tip gaya hidup

• Maintain a healthy diet rich in fruits, vegetables, whole grains, and lean protein
• Stay physically active to support brain health and overall well-being
• Get good quality sleep and address sleep problems with help from a doctor
• Avoid alcohol and smoking
• Keep up with hobbies and activities that bring joy and purpose

Diet dan senaman

A balanced diet like the Mediterranean diet, which includes plenty of vegetables, fruits, whole grains, fish, and healthy oils, may help support brain health. Regular exercise, such as walking or gentle stretching, can improve mood, sleep, and physical strength. Always check with a doctor before starting a new exercise programme.

Kesihatan mental dan kesejahteraan emosi

Alzheimer's can cause feelings of frustration, sadness, fear, and anger in the person and their family. It is common to experience depression or anxiety. Talking to a professional, joining a support group, and staying connected with others can help. If you have thoughts of harming yourself or someone else, call your local emergency number immediately.

Pencegahan

There is no sure way to prevent Alzheimer's, but research shows that healthy lifestyle habits may lower the risk. These include staying physically active, eating a healthy diet, not smoking, limiting alcohol, managing blood pressure and diabetes, staying mentally active, and staying socially connected.

Vaksin

Program saringan

Routine screening for Alzheimer's is not recommended for people without symptoms. However, if you have concerns about your memory, talk to a doctor. Some research studies are looking at brain scans and blood tests to detect early signs, but these are not yet standard.

Komplikasi

Jika tidak dirawat

• Worsening memory loss that makes independent living unsafe
• Increased risk of falls, fractures, and injuries
• Difficulty eating and drinking, leading to weight loss and dehydration
• Infections, especially pneumonia and urinary tract infections
• Behaviour problems like aggression or wandering
• Depression and social isolation

Pandangan jangka panjang

Alzheimer's disease progresses over many years, often 8 to 10 years after diagnosis. While there is currently no way to stop it, treatments and support can help manage symptoms and improve quality of life. Research is ongoing, and there are many sources of hope and help. Planning ahead and getting support early can make a big difference.
