Sundowners

  I have a friend with Alzheimer's who has a noticable behavior change when it gets to be late in the afternoon.  I was told this is a common occurance and that the term for it is "sundowners syndrome".  I can't find anything on this.  Could you help me.

Dear  Amy
     Sundowner syndrome usually occurs in older people with dementia, although it can occur in other medical conditions. It is characterised  by night time wanderings and confusion which can be a problem for family members or care providers. Sundowning or the emergence of severely disruptive behavior such as agitation, paranoia or inability to maintain sleep is a major management issue in the home care of patients with dementia.The sleep disturbance worsens as the disease progresses. Patients with this syndrome should be medically evaluated. Depending on the patient, certain medications or environmental adaptations can be suggested.
     For more information you can refer  to " Comprehensive Text Book of Psychiatry" by Harold I. Kaplan and Benjamin J. Sadock, M.D., seventh edition. For thorough evaluation of your friend by a psychiatrist you may call  Henry Ford Hospital Behavioral Services Clinic at (313)-874-6680. I hope this information is helpful to you. This information is used for general medical educational  purposes only and should not be replaced by evaluation with a physician.
