"Changed Behaviour" series
Most people experience anxiety at some point in their life, but this may be more acute for a person with a learning disability or autism who then develops dementia. If a person has a history of being anxious or of living with a condition - particularly conditions like OCD (Obsessive Compulsive Disorder), phobias or panic disorders - that makes them anxious, developing dementia may then make that worse.
The person's communication skills may have diminished due to their dementia, leaving them frustrated at being unable to express themselves and anxious about the consequences of this.
