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.
Insects such as the linden looper, spring cankerworm, gypsy moth caterpillar, tent caterpillar and the basswood leafminer will all eat the leaves of the American linden. Perhaps the tree's biggest insect nemesis is the Japanese beetle, a bug that can defoliate large areas of the tree.
