Using the nicotine patches is safer than smoking cigarettes, and has the same "awakening" or "improved concentration" that smoking gives to many patients. There are other medications for concentration that affect the blood vessels less than nicotine, and would be safer for these with arterial blockages, or damage, or patients who are older.And Duke Univ is using nicotene patches for the elderly and those with certain thinking problems.LINKPrevious research conducted by the Duke team and others has found evidence that nicotine might benefit people with a variety of disorders -- including schizophrenia, attention deficit hyperactivity disorder and Alzheimer's disease. However, the latest study is the first to examine the drug's effects on people with age-associated memory impairment (AAMI), a common condition among older people characterized by so-called "senior moments."
In a small sample of seniors, the researchers found that four weeks of nicotine treatment halved decision times on a standardized test of memory and increased participants' ability to focus their attention – a skill critical for learning and memory. While receiving nicotine, seniors' assessments of their own memories also showed small but significant improvement.
