The NHS says that dementia symptoms may also include problems with language, such as using words incorrectly, or trouble speaking, as well as movement and difficulties doing daily activities.
It explains: “The symptoms of dementia usually become worse over time. In the late stage of dementia, people will not be able to take care of themselves and may lose their ability to communicate.”
Some dementia risk factors are impossible to change, such as age and genetics, however research suggests other risk factors may also be important, and may be possible to change.
The NHS suggests that risk factors such as hearing loss, untreated depression, loneliness or social isolation, or sitting for most of the day, may also be important.
