Motor performance in detoxified alcoholics.
Detoxified male and female alcoholics (aged 20-49 years) and age-matched controls performed a series of 15-sec target-tapping tasks in which they alternatively marked two target strips with a felt marker as rapidly and as accurately as possible. Consistent with "Fitts' Law" (Fitts PM: J Exp Psych 47:381-391, 1954), a highly linear relationship between movement time and task difficulty was obser...
متن کاملVisual performance and recovery in recently detoxified alcoholics.
In order to assess the impact of chronic alcohol misuse on basic visual functions, we investigated motion perception, visual short-term memory, and visual divided attention in recently detoxified patients and matched controls by means of visual psychophysical tasks. Subjects were tested twice within the first 3 weeks of detoxification in order to assess the potential recovery of visual performa...
متن کاملSodium sensitivity of blood pressure in long-term detoxified alcoholics.
To investigate whether sodium sensitivity of blood pressure participates in the relationship of arterial hypertension to chronic alcohol consumption, 30 alcoholics detoxified from 6 to 12 months and 30 teetotaler controls underwent a dietary sodium manipulation study. They received a daily 55 mmol sodium diet for 7 days, followed by a 260 mmol sodium diet for 7 days. Changes in 24-hour urinary ...
متن کاملHand movement speed and accuracy in detoxified alcoholics.
Detoxified alcoholics (n = 192) were found to be 9.3% slower than age-matched controls (n = 112) with regard to the composite speed (movement time, MT) with which they were able to strike targets of various sizes and distances with a hand-held stylus at onset of a light stimulus (Fitts's Task). Females (n = 102) were 8% slower than males (n = 202), and blacks (n = 103) about 15.6% slower than w...
متن کاملProfound decreases in dopamine release in striatum in detoxified alcoholics: possible orbitofrontal involvement.
The value of rewards (natural rewards and drugs) is associated with dopamine increases in the nucleus accumbens and varies as a function of context. The prefrontal cortex has been implicated in the context dependency of rewards and in the fixated high value that drugs have in addiction, although the mechanisms are not properly understood. Here we test the hypothesis that the prefrontal cortex r...
