When people hear the word dementia, they often think of someone who has problems with memory. While memory is often affected in dementia, this is not always the case. There are many different types of dementia – and each can produce a wide range of symptoms.
A recent case study has even described a 68-year-old man with a rare form of dementia that caused him to develop a fascination with a very specific type of noise. As this type of dementia has only been recently recognised by medical experts, this finding suggests that changes in preferences for sounds may be a key feature of the syndrome.
