Three early warning signs of dementia include changes in short-term memory, problems recalling words in conversation and changes in mood and disposition, according to Healthline. Patients showing signs of early dementia have trouble recalling recent things, such as why they entered a room or remembering what they had for breakfast.
When a patient struggles to find the right word during a conversation, it is possibly an early sign of dementia. These conversations take longer than usual and are difficult to understand, explains Healthline.
Dementia causes a shift in judgment that can appear as personality shifts and changes in overall mood, says Healthline. This includes depression or an extroverted patient who becomes shy.
