Elderly grandma has hbp and chf & has trouble sleeping. she has become very emotional and doesn't make sense. what would calm her safely?

Delirium?: Your grandma needs an urgent assessment with her primary care physician. The mental status changes you describe (sleep disturbance, very emotional, and "doesn't make sense") are consistent with delirium, a confusional state caused by many kinds of medical problems including medication reactions -- but you list no meds. Treatment requires correcting the underlying cause.

Delirium: Acute confusional state, or delirium , is a medical emergency in the elderly. She may have an infection, low oxygen(from chf), or any number of serious medical conditions contributing to her distress and confusion. Older adults present atypically for most symptoms of illness.Emotional lability can be related to delirlium but also reflect a new stroke, depression or a first sign of dementia.
