Dealing with incontinence especially at night with vascular dementia. Costs of product getting very costly. Need suggestions for management.

Not really relevant since it's a man we are talking about, but have people caring for an incontinent woman ever tried using purewicks at home. Those things are magic.

We used the Tenya brand of underwear and peapod mats (3'x5') on the bed and other sizes where necessary. Expensive investment but worth it in the long run.

My husband had advanced Parkinson’s for years with incontinence. I found that Depends overnight were the best but I added an additional liner that can be bought online. These are called “boosters” and do not have the plastic on one side. There is also an apparatus that long-haul truck drivers have used which he can wear at night and the urine is collected in a side bag. I also had a bunch of protection mattress pads that he always slept on so at least I didn’t have to change the entire bed if there was a leak. Hope this helps.
