Overview
Dementia is a degenerative disease that affects the brain, leading to progressive cognitive decline and difficulties with memory, thinking, language, and judgement. Depending on the type, dementia results from damage to different parts of the brain. While dementia is progressive, there are treatments that can help manage symptoms and improve quality of life.
What is Dementia?
Dementia refers to a group of conditions caused by damage to brain cells, which interferes with normal brain function and communication between brain regions. The most common types of dementia are Alzheimer’s disease and vascular dementia, though others include frontotemporal dementia and dementia with Lewy bodies. Dementia affects different areas of thinking, including memory, reasoning, language, and the ability to make decisions or plan.
What Are the Symptoms of Dementia?
Dementia symptoms can vary between people, but some of the most common include:
- Memory loss, especially with recent events
- Confusion about time, place, or familiar people
- Language difficulties, such as struggling to find the right words
- Personality or behavioural changes, including increased anxiety or irritability
- Impaired judgement and difficulty with problem-solving
- Reduced concentration or difficulty completing familiar tasks
Symptoms often begin gradually and may be subtle at first. As dementia progresses, these signs typically become more noticeable and start to interfere with everyday life.
What Does Dementia Look Like?
Dementia can present differently depending on the person and the stage of dementia. In the early stages, signs may include forgetfulness, repeating questions, or withdrawing from social situations. Friends or family may notice personality changes or a loss of interest in hobbies.
As dementia progresses into the middle stage, confusion becomes more frequent, speech may become harder to follow, and daily routines often require more support. In the later stages, a person may lose the ability to recognise loved ones, become immobile, or require round-the-clock care.
Outwardly, dementia may look like:
- Disorientation in familiar places
- Repetitive speech or actions
- Struggling with conversation or understanding
- Withdrawal from social contact
- Neglect of personal hygiene or safety
Recognising these changes early can lead to quicker access to care and planning.
What Causes Dementia?
Dementia is caused by damage to brain cells that affects their ability to communicate with one another. This damage occurs differently depending on the type of dementia:
- Alzheimer’s disease is linked to the build-up of abnormal proteins in and around brain cells, which disrupt their function and lead to gradual cell death.
- Vascular dementia occurs when blood flow to parts of the brain is reduced or blocked, often following a stroke or due to small vessel disease.
- Frontotemporal dementia results from damage to the frontal and temporal lobes of the brain, affecting behaviour, personality, and language.
- Dementia with Lewy bodies involves abnormal protein deposits (Lewy bodies) that affect brain chemistry and disrupt thinking, movement, and alertness.
Common risk factors for dementia include increasing age, a family history of dementia, cardiovascular conditions (such as high blood pressure or diabetes), smoking, and physical inactivity. While some of these risks can’t be changed, others may be reduced through healthy lifestyle choices.
How is Dementia Diagnosed?
Diagnosing dementia involves a series of steps designed to understand your symptoms and rule out other potential causes. The process usually begins with a clinical evaluation and a review of your medical history, followed by cognitive testing to assess areas such as memory, attention, and language.
Blood tests are often carried out to check for issues like vitamin deficiencies or thyroid problems, which can sometimes cause similar symptoms. Brain imaging, including MRI or CT scans, may be used to identify structural changes in the brain that are consistent with dementia.
In certain cases, more detailed neurological assessments are recommended to help determine the specific type and stage of the condition. An early diagnosis can provide clarity, open up access to appropriate care, and support better long-term planning.
What Treatments Are There for Dementia?
Although there is currently no cure, there are several treatments for dementia that can help relieve symptoms. These may include:
- Medication, such as cholinesterase inhibitors or memantine, can manage memory symptoms and improve communication between brain cells.
- Therapies like cognitive stimulation or occupational therapy can support mental function and independence.
- Lifestyle changes, including physical activity, a balanced diet, and social engagement, may support brain health and improve well-being.
Supportive care plays a crucial role – tailored plans can help people with dementia live more comfortably and confidently.
When to Seek Medical Help
If you or someone close to you is experiencing symptoms such as memory loss, confusion, difficulty with language, or changes in personality or judgement, it’s important to speak to a doctor. Early recognition can lead to earlier access to care, support, and planning. You don’t need to wait until symptoms become severe – a conversation at the right time can make a meaningful difference.
