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.
Only one generation of eastern tent caterpillars develops each year. In spring as new leaves develop, the caterpillars leave the eggs and begin to feed and spin silken webbing. After about two days, they begin weaving a tent in a crotch of a branch. As the caterpillars grow, they spin successive layers on the tent.
