Understanding Alzheimer's Dementia: An Overview
Dementia affects over 570,000 people in England, equating to 1 in 6 individuals over the age of 80. While it predominantly impacts older adults, approximately 12,500 people under 65 experience symptoms, termed early-onset dementia. Both men and women are susceptible to this condition.
With an ageing population and improved cardiac health, the number of people living with dementia in the UK is projected to rise significantly, reaching over 1 million by 2025 and over 2 million by 2051. Currently, dementia costs the UK more than £26 billion annually, with two-thirds of these expenses borne by individuals with dementia and their families.
What is Alzheimer's Dementia?
Dementia isn't a single disease but an umbrella term for a range of symptoms resulting from various brain disorders, including:
Alzheimer’s disease
Vascular dementia
Dementia with Lewy bodies (DLB)
Frontotemporal dementia
Dementia pugilistica
Creutzfeldt-Jakob disease
These conditions can cause:
Short-term memory loss
Mood changes
Communication difficulties
Disorientation
Delusions
Impaired cognitive functions
Depression
Weight loss
Behavioural issues like jealousy, paranoia, or aggression
Certain behaviours, such as pathological jealousy, are associated with specific types of dementia like DLB and dementia pugilistica, often linked to head trauma.
Causes of Dementia
Dementia can arise from various factors. Many forms, such as Alzheimer’s and frontotemporal dementia, have genetic links. Dementia with Lewy bodies also shows genetic predispositions. Other causes include:
Head trauma, leading to dementia pugilistica
Oxygen deprivation to the brain (hypoxia), due to strokes, cardiac arrests, or high altitude sickness
Brain tumours that compress brain tissue
Diseases like Huntington’s, Parkinson’s, leukaemia, meningitis, AIDS, syphilis, and liver cirrhosis, often linked to alcohol-related dementia
Recognising Dementia Symptoms
Early identification of dementia is crucial for securing appropriate care. Look out for:
Memory Problems: Repeating stories, forgetting names, missing appointments, or asking the same questions repeatedly.
Word Confusion: Struggling to find words, using vaguely related terms, or resorting to nonsensical words.
Personality Changes: Shifts in behaviour, such as becoming nervous or insensitive.
Depression Symptoms: Unhappiness, social withdrawal, changes in sleep and appetite, and mood swings.
Difficulty with Everyday Tasks: Struggling with complex tasks, leaving activities unfinished, losing things, or placing items in unusual locations.
Disorientation: Confusion in unfamiliar environments, anxiety in stimulating settings, and wandering off in familiar areas.
Differentiate dementia from natural ageing by visiting comprehensive guides like those from alzheimers.org.uk.
Communicating with Someone Who Has Dementia
Effective communication with someone living with dementia involves a calm, distraction-free environment. Ensure:
Eye contact and relaxed, expressive body language
Clear, calm, and expressive voice
Short, simple sentences with pauses for processing
Use of ‘yes or no’ questions to avoid confusion
Holding up options for ‘either/or’ questions
When caring for a loved one, remember to take breaks and seek respite care. Joining a carer’s forum or seeking therapy can provide invaluable support.
