Dementia is one of the biggest killers in the UK with cases rising every year. According to data one in three people born today will be affected by the condition in their lifetime. As a result of the predicted rise in cases, the UK’s leading dementia charity has called for a national network of brain health clinics to help revolutionise dementia care. Executive director of policy and communication at Alzheimer’s Research UK Samantha Benham-Hermetz said: ‘For people living with dementia to receive proper treatment – including the new drugs currently being looked at by regulators – they need to receive a formal diagnosis. ‘But in England, we know that more than a third of over-65s living with dementia never get a diagnosis at all. This is completely unacceptable, as is the underlying diagnosis target of 67 percent. ‘We wouldn’t accept this for any other condition, so we shouldn’t for dementia .”
