Symptoms of Pseudodementia. A person may appear confused, exhibit symptoms that have to do with any of the conditions associated with pseudodementia. For instance, if they are depressed, they may experience depressive symptoms such as sleep disturbance, and complain of memory impairment and other cognitive problems.
Despite the damage they can cause, it is worth noting that trees can be surprisingly resilient in the face of an infestation. Tent caterpillars cause trees to defoliate, which is a problem, but an established tree can withstand 25 percent defoliation without succumbing to any problems.
Forest tent caterpillar moth. The forest tent caterpillar moth (Malacosoma disstria) is a North American moth found throughout the United States and Canada, especially in the eastern regions. The larvae of this species are notorious tent caterpillars. Tent caterpillars do not make tents, but rather, weave a silky sheet where they lie together during molting.
