I never really knew what dementia was until my dad was diagnosed. It has been quite a long journey. It all came out when he had a TIA and Drs did an MRI of his head. 3 yrs later it's all been downhill. He has just started declining really fast. He got constipated spent a couple days in the hospital and now can barely walk sleeps all the time and can't use the bathroom on his own. I can't help but think the end is near. My dad isn't at all the dad I used to know. He always worked or stayed outside working on something. My dad is a Vietnam army vet. He has stayed so strong threw this journey.
