The highest mental health prevalence of 35.4 per cent was reported by a GP service in a care home in Wandsworth that contains a dementia unit.
The Nightingale Home also reported the highest prevalence in England for hypothyroidism, and was in the top five nationally in five other categories.
Ram Awatar, the home’s nursing director, said: ‘We currently have 225 patients, mostly over the age of 80, many of whom have early-onset dementia or moderate dementia.’
