Dopamine modulates executive function, including sustaining cognitive control during mental fatigue. Using event-related functional magnetic resonance imaging (fMRI) during the color-word Stroop task, we aimed to model mental fatigue with repeated task exposures in 33 cocaine abusers and 20 healthy
BACKGROUND
Fatigue and sleep disturbance are common features of multiple sclerosis (MS). Our objectives were to determine cerebrospinal fluid levels of orexin A (hypocretin-1), a hypothalamic peptide involved in sleep, in patients with MS, and correlate them with fatigue, sleepiness, and levels of
Trait impulsivity has been linked to addiction in humans. It has been suggested that drug users with high trait impulsivity levels are more sensitive to subjective drug intoxication. This study assessed whether subjective response to drugs differs between drug users with normal or high levels of
Users of cocaine and/or crack may present symptoms of dysphagia due to changes in anatomical structures caused by the use of these substances. The objective of this study was to investigate the presence of symptoms suggestive of dysphagia in users of cocaine and/or crack seeking treatment, as well
BACKGROUND

Four hundred seventy-nine drug abusing adolescent patients enrolled in seven Straight, Inc. Adolescent Drug-Abuse Treatment Programs in five geographic regions across the United States were studied to determine the severity and patterns of cocaine abuse. Of these, 341 admitted to cocaine use and
To determine the effects of a variety of doses of cocaine on endurance capacity, rats were injected intraperitoneally with either 0.1, 0.5, 2.5, 12.5, or 20 mg/kg body wt 20 min before running to exhaustion at 26 m/min up a 10% grade. Animals given saline ran 116 +/- 9 (SE) min. At doses of 12.5 and
Because cocaine causes a rapid sympathetic response and central euphoria, we tested whether it would improve endurance or alter carbohydrate metabolism during high-intensity activity. Thirty male rats (10 animals/group) were injected intraperitoneally with either saline (S) or one of two doses of
Cocaine (2 mg/kg) was given orally to 13 healthy volunteers and physiologic, subjective, attentional and performance effects were measured over a period of 4 h. Posner's reaction time paradigm measured the effects of cocaine on performance and on attention to visual cues. Cocaine increased heart
Clinical and preclinical evidence suggests that cocaine exposure hastens progression of the HIV disease process. An established active, euphoric dose of cocaine (20 mg/kg) was administered to SCID mice according to a regimen consistent with exposure to the drug by cocaine-abusing HIV-infected
The frequencies of 15 self-reported symptoms of cocaine withdrawal were compared in 75 subjects to the symptoms listed as criteria by DSM-III and DSM-III-R for either amphetamine or cocaine withdrawal. Three of the four most frequently reported symptoms, depression (75%), sleep disturbance (71%),
BACKGROUND
Disulfiram has demonstrated efficacy in six randomized clinical trials for the treatment of cocaine dependence, but is rarely used in clinical settings because of safety concerns.
OBJECTIVE
What are the common and serious side effects of disulfiram in cocaine-dependent individuals with
Fatigue is a common symptom in substance abuse disorders. The most frequent and relevant addiction disorders like alcoholism and dependence of illegal drugs like THC, opioids, cocaine, ecstasy, psycho-stimulants, and GHB/GBL (gamma hydroxybutyrate/gamma butyrolactone; "Liquid Ecstasy") are
