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.
A: Tent caterpillars and gypsy moths eat leaves in the spring. Deciduous trees (trees that lose their leaves each fall) can regrow a new set of leaves by July and can usually withstand 2-3 successive years of defoliation (removal of leaves) without being killed.
