Alzheimer’s disease is the most common cause of dementia. The word dementia describes a set of symptoms that can include memory loss and difficulties with thinking, problem-solving or language. These symptoms occur when the brain is damaged by certain diseases, including Alzheimer’s disease. This factsheet describes the symptoms of Alzheimer’s disease, how it is diagnosed, and the factors that can put someone at risk of developing it. It also describes the treatments and support that are currently available. The symptoms of Alzheimer’s disease are generally mild to start with, but they get worse over time and start to interfere with daily life.
There are some common symptoms of Alzheimer’s disease, but it is important to remember that everyone is unique. Two people with Alzheimer’s are unlikely to experience the condition in exactly the same way.
For most people with Alzheimer’s, the earliest symptoms are memory lapses. In particular, they may have difficulty recalling recent events and learning new information. These symptoms occur because the early damage in Alzheimer’s is usually to a part of the brain called the hippocampus, which has a central role in day-to-day memory. Memory for life events that happened a long time ago is often unaffected in the early stages of the disease according to Dr Winnie Lim Khoo – Adult Neurologist in Manila Philippines
Memory loss due to Alzheimer’s disease increasingly interferes with daily life as the condition progresses. The person may:
- lose items (eg keys, glasses) around the house
- struggle to find the right word in a conversation or forget someone’s name
- forget about recent conversations or events
- get lost in a familiar place or on a familiar journey
- forget appointments or anniversaries.
