ChEIs produce small, short-lived improvements in cognitive function in mild to moderate dementia, which may not translate into clinically meaningful effects. Marginal benefits are seen with severe disease, long-term treatment, and advanced age. Cholinergic side effects, including weight loss, debility, and syncope, are clinically significant and could be especially detrimental in the frail elderly population, in which the risks of treatment outweigh the benefits. Memantine monotherapy may have minimal benefits in moderate to severe dementia, balanced by minimal adverse effects.

The use of very-low-dose methadone in conjunction with adjuvant haloperidol resulted in excellent pain control without dose escalation or opioid-induced hyperalgesia, for both cancer and noncancer diseases. We conclude that low-dose methadone should be part of first-line treatment in palliative pain management.
