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.
When numerous, the insect defoliates many other fruit trees as well as deciduous forest and shade trees including birch, oak, willow, poplar, and beech. The forest tent caterpillar prefers the foliage of sugar maple, poplar, ash, oak, birch, red gum, and black gum. The early spring feeding often results in destruction of the buds before they have a chance to open.
