A family with coexistence of hypotension, recurrent respiratory infection, motor tics, obsessive compulsive disorder, major depressive disorder, early onset osteoporosis, low body mass index, bulimia nervosa and healthy aging with longevity is described. The family members had hyposexual behavior, less tendency for spirituality, had no insomnia but a tendency towards increased somnolence, no addictive behaviour, had more bonding and affectionate behavior and were less creative with an average IQ. There was no vascular thrombosis, systemic neoplasm and neuronal degeneration in the index family. All members of the family were left hemispheric dominant. The level of serum digoxin, HMG CoA reductase activity and dolichol was found to be decreased in all with a corresponding increase in RBC Na(+)-K(+) ATPase activity and serum ubiquinone magnesium level. There was increase in tyrosine catabolites and a reduction in tryptophan catabolites in serum. Total and individual glycosaminoglycan fractions, carbohydrate residues of glycoproteins, glycolipids, activity of GAG degrading enzymes and glycohydrolases were decreased in serum. The concentration of RBC membrane total GAG and carbohydrate residues of glycoproteins increased while cholesterol : phospholipid ratio of membrane decreased. The activity of free radical scavenging enzymes were increased while the concentration of free radicals decreased significantly. The same biochemical patterns were observed in left hemispheric dominance as opposed to right hemispheric dominance. The significance of these findings in the pathogenesis of these disorders is discussed.

The isoprenoid pathway produces an endogenous membrane Na+-K+ ATPase inhibitor, digoxin, which can regulate neurotransmitter and amino acid transport. Digoxin synthesis and neurotransmitter patterns were assessed in eating disorders. The patterns were compared in those with right hemispheric and left hemispheric dominance. The serum HMG CoA reductase activity, RBC membrane Na+-K+ ATPase activity, serum digoxin, magnesium, tryptophan catabolites (serotonin, quinolinic acid, strychnine, and nicotine), and tyrosine catabolites (morphine, dopamine, and noradrenaline) were measured in anorexia nervosa, bulimia nervosa, right hemispheric dominant, left hemispheric dominant, and bihemispheric dominant individuals. Digoxin synthesis was increased with upregulated tryptophan catabolism and downregulated tyrosine catabolism in those with anorexia nervosa and right hemispheric chemical dominance. Digoxin synthesis was reduced with downregulated tryptophan catabolism and upregulated tyrosine catabolism in those with bulimia nervosa and left hemispheric chemical dominance. The membrane Na+-K+ ATPase activity and serum magnesium were decreased in anorexia nervosa and right hemispheric chemical dominance while they were increased in bulimia nervosa and left hemispheric chemical dominance. Hypothalamic digoxin and hemispheric chemical dominance play a central role in the regulation of eating behavior. Anorexia nervosa represents the right hemispheric chemically dominant/hyperdigoxinemic state and bulimia nervosa the left hemispheric chemically dominant/hypodigoxinemic state.

The case report of a family with coexistence of hypotension, recurrent respiratory infection, motor tics, obsessive-compulsive disorder (OCD), major depressive disorder, early onset osteoporosis, low body mass index, bulimia nervosa, and healthy aging with longevity is described. The family members had hyposexual behavior and less tendency toward spirituality. They did not have insomnia, but they did display tendency toward increased somnolence. No addictive behavior was observed. The family demonstrated a high level of bonding and affectionate behavior, and they were less creative, with an average intelligence quotient (IQ). There was a total absence of vascular thrombosis, systemic neoplasms and neuronal degeneration in the indexed family. All members of the indexed family were left hemispheric dominant. The levels of serum digoxin, HMG-CoA reductase activity, and dolichol were found to be decreased in the members of the indexed family, with a corresponding increase in red blood cell (RBC) Na(+)-K+ ATPase activity, serum ubiquinone and magnesium levels. There was increase in tyrosine catabolites and a reduction in tryptophan catabolites in the serum. The total and individual glycosaminoglycan fractions, carbohydrate residues of glycoproteins, activity of glycosaminoglycans (GAG) degrading enzymes, and glycohydrolases were decreased in the serum. The concentration of RBC membrane total GAG and carbohydrate residues of glycoproteins increased, while the cholesterol: phospholipid ratio of the membrane decreased. The activity of free radical scavenging enzymes were increased, while the concentration of free radicals decreased significantly. The same biochemical patterns were observed in left hemispheric dominance as opposed to right hemispheric dominance. The significance of these findings in the pathogenesis of these disorders is discussed.
