Dementia can be a very scary and isolating condition for the patient and their carers and whilst you can provide a safe and supportive environment they may require more support than you can provide. It would be useful if you have a list of NHS, charitable and voluntary organisation that you can signpost.
NHS.uk has a vast amount of information and advice about the condition.
There are a number of voluntary and charity organisations that provide national and local help, through printed and online literature, helplines and local support groups, these include:
There are also a number of online communities that are available such as Talking Point, Carers UK Forum and Carers Trust Forum which allows patients with dementia and their carers to talk to other people in their situation.
You may also have local groups and organisations that support people with dementia.
