Alzheimer's disease

What is Alzheimer's disease? Alzheimer's disease (AD) is the most common form of dementia among older people. Dementia is a brain disorder that seriously affects thinking and memory skills. If you have AD, it can impair your ability to reason or learn new skills until it becomes difficult to complete daily activities. AD begins slowly over many years. It first involves the parts of the brain that control thought, memory, and language. It may be mistaken for normal memory changes with aging. However, AD is not a normal part of aging. The brain changes from the disease lead to symptoms that get worse over time. What are the symptoms of Alzheimer's disease? People with AD may have trouble remembering recent events or the names of people they know. Behavior may vary from person to person and day to day. AD progresses in stages. Late-onset AD occurs in adults aged 65 and older, which is when most people develop the disease. Early-onset AD happens before age 65, which is not common. Some symptoms of AD can include: Getting lost in familiar places Repeating the same question Not recognizing family members Having trouble speaking, reading, or writing Not taking care of yourself, such as not bathing or eating poorly In AD, over time, symptoms get worse. Later on, people with AD may become anxious or aggressive or wander away from home. Eventually, they need total care. This can cause great stress for family members who must care for them. Who is more likely to develop Alzheimer's disease? Researchers don't fully understand what causes AD. Age is the biggest risk factor. Your risk is also higher if a family member has had the disease. Although people who develop Alzheimer's don't always have a history of the disease in their families. Researchers believe the causes of AD may be a combination of age-related changes in the brain, along with genetic, health, and lifestyle factors. Some medical conditions that are associated with a higher risk of AD include: Hearing loss Depression Mild cognitive impairment Concussion or other traumatic brain injury (TBI) A related problem, mild cognitive impairment (MCI), causes more memory problems than normal for people of the same age. Many, but not all, people with MCI will develop AD. How is Alzheimer's disease diagnosed? Some health conditions can cause memory loss or symptoms like AD. Talk with your health care provider if you're having noticeable changes in your memory. To determine if your symptoms are related to AD and not normal aging or another health condition, your provider may: Review your medical history and any medicines you're taking Conduct tests to check your memory, thinking, and problem-solving skills Ask about changes in behavior or personality Do tests to rule out any medical or mental health conditions Refer you to a provider that specializes in caring for older adults Recommend a neurologist, a doctor who specializes in treating diseases of the brain and nervous system What are the treatments for Alz…
