There is often a discrepancy between the in-tact social behavior of Alzheimer’s patients and the more hidden cognitive changes that are taking place, and this can be deeply confusing. My mother remained wonderfully warm and hospitable and friendly almost to the end of her illness, offering to make a cup of tea, or a plate of chicken soup, to whoever she spoke to, even when she was living in a small room of a geriatric facility, with no ability to manage her own life. Those aspects of her nature were barely damaged by the illness, though she had no idea to whom she was being so loving. This “confabulation”, i.e. talking as though one is keeping up with the conversation, is an often heartbreaking display of the effort to maintain pretenses.
Interestingly, art productions of patients can be useful indicators of underlying decline in mental functioning. As an art therapist in a unit, I could often point out basic changes in graphic abilities, such as confusion on the page, uncontrolled and wild composition, simplification of images, distortions and fragmentation of images. This insight through the artwork was helpful to the rest of the therapeutic team who might be missing fundamental and hidden difficulties the patient was experiencing. When the changes were pointed out to the staff, they were able to understand and make adaptations to changes in their functioning.
