What is Alzheimer’s?
Alzheimer’s disease is the most common form of dementia, in which the brain’s nerve cells gradually break down. The disease primarily affects language and the ability to remember. It can also cause difficulties with orientation and decision-making. The progression is slow but continuous, developing over several years. Alzheimer’s is most common in older adults, but it can also affect people under the age of 65.
Causes of Alzheimer’s disease
The exact cause of Alzheimer’s disease is not fully understood, but research suggests that it develops through a combination of age, genetic factors, and biological changes in the brain. One clear finding is that people with Alzheimer’s have accumulations of proteins in the brain, which damage the nerve cells.
Common symptoms of Alzheimer’s disease
The symptoms develop gradually as the disease progresses and can be easy to overlook at first. Early signs often involve impaired memory and language abilities, while later stages affect behavior and daily functioning.
Early symptoms of Alzheimer’s
- Impaired memory: difficulty remembering new information, even though older memories remain.
- Language difficulties: trouble finding words or following conversations.
- Reduced sense of orientation: difficulty finding one’s way, even in familiar environments.
- Poor concentration: easily distracted and difficulty planning simple activities.
Symptoms in later stages
- Behavioral changes: increased anxiety, irritability, or apathy.
- Difficulties managing daily tasks: reduced ability to handle hygiene, cooking, and finances.
- Speech and communication problems: difficulty expressing oneself and understanding others.
- Reduced mobility: stiffness and balance problems that increase the risk of injury.
How is Alzheimer’s diagnosed?
Alzheimer’s disease is diagnosed based on several factors, including medical assessment, memory testing, and brain imaging such as MRI scans. Sometimes blood tests or a lumbar puncture are performed to exclude other causes of the symptoms. An early diagnosis is important for planning patient support and treatment.
Treatment and support
There is currently no cure for Alzheimer’s, but medications can slow the progression of the disease and relieve symptoms. Support services are an important part of the treatment plan to help maintain quality of life as the disease advances.
- Medication: cholinesterase inhibitors and memantine can improve memory and cognition in certain stages of the disease.
- Rehabilitation: cognitive training and structural support help the patient manage daily life for a longer period.
- Support for relatives: counseling and respite services help reduce the burden on caregivers.
- Physical activity and social stimulation
When should you seek medical care?
Seek medical care if you or a loved one experience persistent memory problems, noticeable personality changes, or new difficulties handling everyday activities. Early diagnosis is important to ensure timely support and treatment.
