The most common form of dementia is Alzheimer's disease. alcohol-related dementia, AIDS-related dementia and Creutzfeldt-Jakob disease.
Circadian rhythm sleep disorders (CRSDs) are characterized by normal sleep patterns that occur at irregular times of the day, often due to misalignment with the internal circadian clock. CRSDs are particularly common in elderly people due to changes in their circadian rhythms brought on by aging, as well as reduced exposure to natural light and a decrease in physical activity. Examples of CRSD include advanced sleep phase disorder (ASPD), when patients fall asleep and wake up at relatively early times; and irregular sleep-wake disorder (ISWD), when one’s daily sleep patterns are broken up into chunks over a 24-hour period, rather than in one prolonged phase.
Parkinson’s patients often have insomnia that comes and goes through the course of the disease, as well.
Nonpharmacologic interventions should be used first before medication to promote sleep is considered.

He had Alzheimer's and was living in a top-notch long-term care facility, with his depression and sleep disruptions and I'm miserable with his.
"Many families are aghast at the very idea of putting their demented loved ones on psychiatric medications. They fear they'll be 'drugged into submission.'. She continued.
After about three weeks it paid off. His angry outbursts decreased dramatically, although he'd still have an occasional fit. He began sleeping more at night and napping less during the day.
"So he'd still be demented, but might be less depressed and angry? And might start sleeping better?". "That would be wonderful," I said.
He was up to 113.
He began trying it for his wife, monitoring her sleep pattern with a He noted that Alzheimer's patients are reported to have little or no REM sleep. had been sleeping through the night without benefit of other sleep aids, and.
Some research indicates that beta-adrenergic blockers actually worsen behavior and cognitive function in Alzheimer's disease due to the preexisting impairment of cholinergic and serotonin systems. Admittedly this subject confuses me. http://www.nature.com/?file=/npp/journal/v28/n7/full/1300163a.html http://www.nature.com/?file=/npp/journal/v28/n7/full/1300163a.html.
in less than 5 minutes post dosing with 1 or 2 mg. However blocking of catecholamine receptors is relatively rapid and better fits with the observation that prazosin is fast acting and can quell delusions, irritability, aggressiveness, rage, etc.
Alzheimer's disease could be treated with a sleeping pill, according to new the animal model showed these can be relieved with medication.
Correct spread of the waves requires a precise balance to be maintained between the mix of excitation and inhibition of nerve cells. His team also succeeded in decoding the defect at the molecular level.
In the Alzheimer models, this balance was disturbed by the protein deposits, so that inhibition was reduced.
Last year a Canadian study linked taking benzodiazepines for three months or more to a 50 per cent increased risk of Alzheimer’s. At least six million prescriptions are issued for the drugs annually in England.
Alzheimer’s patients frequently suffer from sleep disorders, mostly even before they become forgetful, and the animal model showed these can be relieved with medication.
Dr Marc Aurel Busche said: “But, these findings are of great interest for two reasons: firstly, mice and humans have the same sleep oscillations in the brain - the results are thus transferrable.
Experiments on mice with dementia found small doses of commonly prescribed tablets called benzodiazepines improved their sleep and brain function.
The slow brain waves seen in deep sleep, also known as slow oscillations, are vital for our ability to learn, think and remember.
Explained Dr Busche: “The slow oscillations do still occur, but they are no longer able to spread properly.
These electrical waves wash across the brain, roughly once a second, 1,000 times a night, and are formed via a network of nerve cells in the cortex, and then spread out into other parts, such as the hippocampus.
There are 850,000 Alzheimer’s patients in the UK, with numbers rising because of the ageing population.
