Difficulty multitasking and/or resuming a task after an interruption and
getting organized are indicative of impaired executive functioning.
The primary neurotransmitter hypothesized to be involved in delirium
is acetylcholine, and the major neuroanatomical area is the reticular
formation.
Delirium is associated with acute onset, impaired memory-more short-
term than long-term, prominent hallucinations, and grossly impaired
judgment.
Cholinesterase Inhibitors Donepezil, rivastigmine, or galantamine may
be used for clients with mild, moderate, or severe dementia
associated with Alzheimer’s disease. These drugs act by inhibiting
acetylcholinesterase, thus improving cholinergic function, and
increasing the circulation of acetylcholine. Memantine is used for
clients with moderate to severe dementia associated with Alzheimer’s
disease. This drug selectively blocks the effects of abnormal
glutamate release, an excitatory neurotransmitter. Physostigmine
salicylate, 1 to 2 mg intravenously or intramuscularly, may help in
treating delirium when the underlying condition is anticholinergic
toxicity Boland & Verduin, p. 228).
