Caffeine consumed 6 hours before bedtime reduced sleep by more than 1 hour

A new study shows that caffeine consumption even six hours before bedtime can have significant, disruptive effects on sleep."Sleep specialists have always suspected that caffeine can disrupt sleep long after it is consumed," said American Academy of Sleep Medicine President M. Safwan Badr, MD.
Caffeine can disrupt sleep hours later

Drinking coffee might be a nice way to round off the evening meal or perk you up in the late afternoon, but it may well disrupt your sleep hours later when you retire for the night, according to a new study reported this week.

Caffeine and opening the eyes have additive effects on resting arousal measures. [2011.10]
CONCLUSIONS: Caffeine and opening the eyes have additive effects on two measures of arousal, increasing SCL and reducing global EEG alpha. However, the independent variable effects are not equivalent, suggesting that one or both measures reflect additional non-arousal processes. SIGNIFICANCE: As caffeine is widely used by both children and adults, knowledge of the additivity of arousal effects of caffeine and opening the eyes is important in controlling participant state in EEG studies. The current results confirm the use of mean global alpha amplitude as a measure of resting-state arousal, but also point to non-arousal effects of visual input.

Caffeine ingestion, affect and perceived exertion during prolonged cycling. [2011.08]
Caffeine's metabolic and performance effects have been widely reported. However, caffeine's effects on affective states during prolonged exercise are unknown...
Effect of a single and repeated dose of caffeine on antigen-stimulated human natural killer cell CD69 expression after high-intensity intermittent exercise. [2011.07]
Several studies investigating the effect of caffeine on immune function following exercise have used one large bolus dose of caffeine. However, this does not model typical caffeine consumption... These findings suggest that although one large bolus dose of caffeine attenuated the exercise-induced increase in antigen-stimulated NK cell CD69 expression 1 h following strenuous intermittent exercise, this attenuation at no point fell below pre-supplement values and caffeine does not appear to depress NK cell CD69 expression.
The analgesic and antiemetic efficacy of gabapentin or ergotamine/caffeine for the treatment of postdural puncture headache. [2011.06.01]
PURPOSE: We investigated the analgesic and antiemetic efficacy of gabapentin or ergotamine/caffeine (Cafergot), in addition to conservative treatment consisting of bed rest and adequate fluid intake, for the treatment of postdural puncture headache (PDPH)... CONCLUSIONS: Gabapentin significantly reduced pain, nausea and vomiting compared to Cafergot in patients with PDPH. Lastly, we hypothesize that the gabaergic action of gabapentin, perhaps combined with other mechanisms, such as calcium channel blockade, may be responsible for its remarkable effects on PDPH.
Clinical Trials Related to Cafcit (Caffeine)
Does Caffeine Affect the Sensitivity of Adenosine Perfusion Scans? [Suspended]
We are studying the affect of caffeine on the sensitivity of detecting coronary artery
disease (blockages in the blood flow to the heart) with adenosine tracer scans. Adenosine is
a drug used routinely in patients to relax heart blood vessels in order to assess for the
presence of coronary artery disease. Often, if patients have had caffeine, the adenosine
scan is not used because of the belief that caffeine may reduce the ability to detect
coronary artery disease. We would like to test whether caffeine affects our ability to
detect coronary artery disease with adenosine tracer scanning. We will perform an imaging
study of the heart with adenosine after you have received caffeine.
Neurophysiological Reserve With Caffeine Manipulation [Not yet recruiting]
The objective of this study is to verify if there is a neurophysiologic reserve when
caffeine and placebo perceived as caffeine are manipulated in closed- and opened-loop
exercises. Parameters of excitability level of skeletal muscle and Central Nervous System
(CNS), and peripheral metabolism will be measured
Efficacy of Caffeine, With and Without Biperiden, as a Maintenance Treatment for Cocaine Dependence [Recruiting]
The aim of this study is to assess the efficacy of caffeine compared to placebo as a
maintenance treatment for cocaine dependence. Caffeine potentiation with biperiden will be
Ninety patients with snorted/sniffed cocaine dependence will be randomized to receive
caffeine (300 - 1200 mg t. i.d.) plus biperidene (8 mg b. i.d.) caffeine (300 - 1200 mg
t. i.d.) with placebo or placebo during 10 days in an in-hospital setting.
Caffeine for Excessive Daytime Somnolence in Parkinson's Disease [Recruiting]
Many patients with Parkinson's disease (PD) have sleep problems, including excessive
sleepiness during the day. This is probably due to degeneration of sleep-regulating areas
in the brain. At present, the only treatment for sleepiness in PD is modafinil, which is
expensive and only partially effective. There is another potential treatment for sleepiness
that is used worldwide, is inexpensive, well tolerated and safe - namely, caffeine. There
have also been suggestions that caffeine may slow the progression of degeneration in PD,
since coffee non-drinkers are at higher risk of developing PD. PD patients, even with
severe sleepiness often do not use caffeine. It is unclear whether this is because their PD
makes their sleepiness unresponsive to caffeine, because they cannot tolerate it, or whether
this reflects their lifelong habit of non-use. This proposal outlines a trial in which
patients with excessive sleepiness will be given caffeine or placebo (no therapy) in a
blinded fashion. In this way, the effect of caffeine on sleepiness and motor symptoms can
be directly analyzed. In addition, these findings can be used to test the tolerability of
caffeine, to help plan a larger-scale study testing whether caffeine can slow the
progression of PD
Comparison of Caffeine Reduction and Anticholinergic Medications for Treatment of Overactive Bladder [Recruiting]
The purpose of this study is to assess the effects of caffeine reduction/elimination on
urinary symptoms in women with overactive bladders and compare this therapeutic approach to
anticholinergic therapy. We hope to show a reduction in symptoms with caffeine reduction and
determine how effective caffeine reduction is compared to medication. If caffeine reduction
is shown to be beneficial, women may be encouraged to use this strategy before resorting to
