[Solved]: Mr. Stone is 87 years old and lives in a long- term car

Mr. Stone is 87 years old and lives in a long- term care facility. He has cataracts and a long history of chronic confusion. Each day he spends hours looking for his glasses. He says, I always leave my glasses at my office. But I can drive to work without them. Ive never needed them for driving. Get my tools. How can I go to work without them? I have so much to do before my vacation. Is this delirium, dementia or depression? Provide rationale for your answer.
