An introduction to changes in people's mental health
If there are any concerns about a person’s mental health, seek professional advice. Reassurance, distraction or being socially and mentally engaged in activities may help. Medication may help in other cases.
What is anxiety?
Anxiety is common in people with dementia and can affect people at any stage of the condition.
- While anyone can be anxious in certain situations, anxiety is a mental health issue when the person is feeling anxious over a period of time, in situations we wouldn’t expect, and/or it’s affecting their quality of life
- Anxiety is the body’s flight or fight reaction and it may be expressed by changes in behaviour
- The person may become agitated or fearful, perhaps they seek constant reassurance from you or follow you or family carer around.
What is depression?
Depression is a common mental disorder which impacts upon a person’s feelings, behaviour and thoughts.
- It can have a range of symptoms, including low mood, tearfulness, irritability, a lack of interest and pleasure, changes to appetite, sleep and energy levels
- These symptoms can impact how a person with dementia behaves, and often comes hand-in-hand with dementia
- As many of the symptoms of depression overlap the symptoms of dementia, it often gets missed and therefore people do not receive the treatment required
- Depression can lead to suicidal thoughts. Any concerns must be reported immediately.
What is psychosis?
Psychosis describes the distortion of a person’s perception of reality, often accompanied by delusions and/or hallucinations.
- A delusion is an irrational unfounded belief for example that people are living in the loft, or their partner is being unfaithful
- Hallucinations are seeing, hearing, smelling, sensing things other people can’t
- Typical visual hallucinations include seeing small animals or children
- It’s important to realise that these experiences are very real to the person and may be distressing, so arguing with them or telling them that it is not real often makes the person more distressed.
In their 2010 report, the Institute of Alcohol Studies found that 60 per cent of older people admitted to hospital for confusion, falls at home, chest infections and heart failure may have unrecognised alcohol problems.
- Older people are more often solitary drinkers and it is often ‘hidden’ or overlooked by health care professionals
- The effects of alcohol are widely reported, but these will be more noticeable in an older person and can result in anxiety, depression and poor sleep, liver and kidney problems, self-neglect and/or malnutrition, memory problems, confusion, poor balance and falls.
