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.
Problem insects that affect arborvitaes are leaf miners, bag worms, aphids and spider mites. Bag worms sometimes known as tent caterpillars are large and easy to spot; loss of leaves because of the wormsâ feeding is evident. The other insects may not be so easily seen.
