The value of afternoon glucose tolerance testing in the diagnosis, prognosis and rational treatment of �early chemical diabetes�. A five-year experience

Unlocking the Energy Dynamics of Executive Functioning: Linking Executive Functioning to Brain Glycogen

“…Reid et al, 1974;Roberts, 1968;Whichelow et al, 1974). For instance, one study examined glucose tolerance during continuous darkness among men in the Antarctic who slept during the daytime hours and were awake during the nighttime hours (Campbell, Jarrett, Rutland, & Stimmler, 1975).…”

“…Several studies on both humans and other animals using a variety of methods have demonstrated this pattern, (e.g., oral or intravenous glucose injection, morning or afternoon meal consumption) with glucose tolerance test results showing that blood glucose levels reach a higher point and come down slower in the evening than they do in the morning, suggesting that the insulin is less sensitive (Alcalay, Labram, Deschamps, & Lestradet, 1971;Aparicio et al, 1973;Ben-Dyke, 1971;Bowen & Reeves, 1967;Carrol & Nestel, 1973;Jarrett & Keen, 1969Mayer et al, 1976;Oakley et al, 1973;D.D. Reid et al, 1974;Roberts, 1968;Whichelow et al, 1974). For instance, one study examined glucose tolerance during continuous darkness among men in the Antarctic who slept during the daytime hours and were awake during the nighttime hours (Campbell, Jarrett, Rutland, & Stimmler, 1975).…”

“…Similar to studies on glucose intolerance, several studies have linked diabetes to impaired executive functioning. People with diabetes are more likely than people without diabetes to exhibit signs of difficulties controlling attention (Lane et al, 1988; Lustman, Frank, & McGill, 1991; Rovet & Ehrlich, 1988; Zhao & Liu, 1999), regulating emotions (Barglow, Hatcher, Edidin, & Sloan-Rossiter, 1984; Eren, Erdi, & Özcankaya, 2003; Fabrykant & Pacella, 1948; Fris & Nanjundappa, 1986; Lustman, Griffith, Clouse, & Cryer, 1986; Popkin, Callies, Lentz, Colon, & Sutherland, 1988; Wells, Golding, & Burnam, 1989; Wilson 1951), and coping with stress (Barglow, Hatcher, Berndt, & Phelps, 1985). They also perform poorly on measures of intelligence (Rovet, Ehrlich, & Hoppe, 1987; Ryan, Longstreet, & Morrow, 1985; Ryan, Vega, & Drash, 1985; Ryan, Vega, Longstreet, & Drash, 1984) and are more impulsive (Lustman et al, 1991), more likely to abuse alcohol (Goodwin, Hoven, & Spitzer, 2003; Rehm et al, 2003), and more aggressive (Swift, Seidman, & Stein, 1967).…”

Diurnal Variations of Food Consumption, Plasma Glucose and Plasma Insulin Concentrations in Lean and Obese Hyperglycaemic Mice

“…An appreciation of these variations has improved both the diagnosis and treat ment of disorders of carbohydrate metabolism (Roberts, 1968;Sensi et al, 1973;Goschke et al, 1974;Loreti et al, 1974;Walsh et al, 1974).…”
