Jewish Care's Pesach appeal focuses on how its support enables an 87-year-old Redbridge man to continue to look after his wife, who has dementia and Parkinson's disease.
David and Yvonne Rein met at a Jewish club in Stamford Hill and recently celebrated their 60th wedding anniversary.
When Mrs Rein was diagnosed last year, her husband was determined to keep her at home and he is grateful to Jewish Care for providing four hot dinners a week through its meals-on-wheels service. Mrs Rein also attends the charity's local Dennis Centre, helping those with dementia or memory impairment.
Mr Rein said that Pesach was a particularly stressful time. "Everything has to be changed in the house and you have to buy special food. It's difficult for me because I look after my wife full-time.
"I'll be going to my son's for Seder night. The rest of the time I'll have to cope the best I can. So it's particularly good to get the meals [from Jewish Care]. I couldn't possibly do that at home. I rely a lot on Jewish Care.They make things much easier. Without them, I'd be lost."
It costs £1.1 million annually to keep Jewish Care's dementia day centres open. It is hoped the appeal will raise at least £200,000 for the day centres, memory way cafés, meals on wheels and other services for those living with dementia.
