Can Alzheimer's patients develop temper tantrums?

Absolutely. Loss of self-monitoring and disinhibition of emotional control is a potent combination, often leading to temper tantrums, aggressivity, foul language. Any dementia with those features can have similar symptoms.
Yes, but. There may be some pharmacological interventions which can control or mitigate such events. Exelon patch seems to help aggression, and hallucinations; Namenda seems to assist agitation; Depakote may also help agitation, and have seen some benefit on behaviour from lyrica (pregabalin). Would hope that drugs such as major tranquilizers be avoided due to increased risks in the alzheimer's group.

Try more potent drug. These problems are common and occur as the disease progresses. Namenda may help agitation, and Exelon (rivastigmine) has been shown to help aggression, but if the temper tantrums become violent, it is best to try major tranquilizers such as seroquel to prevent harm. (but these drugs do have risks and must be used with caution). Read more...
