Alzheimer's patient. Caustic burns caused by ingestion of dishwasher powder, seen on the mouth of an 82 year-old female patient with Alzheimer's disease. Alzheimer's disease is the most common cause of senile dementia in old age. Although it's cause is not known, a degeneration of brain tissue occurs. This causes a progressive deterioration in a patient's personality over time, including memory disorders, confusion and disorientation. Loss of sensory and motor functions occur in the final stages during which the patient may require full-time attention.
