Semantic dementia is a variant of Frontotemporal dementia (FTD) and can be the cause of younger onset dementia.

It’s a very rare progressive neurodegenerative syndrome which results in the general knowledge that has been learned throughout life to lose its meaning.

Symptoms include:

  • Behaviour and personality changes
  • Difficulty spelling and pronouncing words accurately
  • Difficulty recognising people
  • Addictive or compulsive behaviour
  • Apathy or depression
  • Able to operate machinery or drive but unable to understand the process or the risks involved.
