8 Possible Causes for Attention Deficit Disorder - in Those Who Stop Treatment, Defective Myelin Formation if Left Untreated, Mental Processing Speed Decreased

  • Classical Phenylketonuria

    Abstract Indirect measurements have previously suggested that patients with classical phenylketonuria (PKU) do not convert significant amounts of phenylalanine to tyrosine. Low-dose continuous infusion techniques employing [2H5]phenylalanine and [2H2]tyrosine were used to quantitate in vivo phenylalanine[…][ncbi.nlm.nih.gov]

  • Vitamin D Deficiency

    “The associations between low vitamin D levels and increased negative and depressive symptoms, and decreased [mental] processing speed and verbal fluency are good arguments[independent.co.uk]

  • Hyperpyrexia

    Some of the neurotoxic effects of hyperpyrexia on the brain include seizures, decreased cognitive speed, mental status changes, coma, and even death.[ncbi.nlm.nih.gov] Pyrexia is a physiological response through which the immune system responds to infectious processes.[ncbi.nlm.nih.gov]

  • Stimulant

    CNS stimulants (CNS stands for central nervous system) are medicines that stimulate the brain, speeding up both mental and physical processes.[drugs.com] They decrease the need for sleep, reduce appetite, improve confidence and concentration, and lessen inhibitions.[drugs.com]
