ADHD is now a well-validated clinical diagnosis in children and adults, and the debate in the scientific community mainly centers on how it is diagnosed and treated. ADHD was officially known as attention deficit disorder (ADD) from 1980 to 1987; prior to the 1980s, it was known as hyperkinetic reaction of childhood. Symptoms similar to those of ADHD have been described in medical literature dating back to the 18th century. Signs and symptoms
Inattention, hyperactivity (restlessness in adults), disruptive behavior, and impulsivity are common in ADHD. Academic difficulties are frequent as are problems with relationships. The symptoms can be difficult to define, as it is hard to draw a line at where normal levels of inattention, hyperactivity, and impulsivity end and significant levels requiring interventions begin.According to the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and its text revision (DSM-5-TR), symptoms must be present for six months or more to a degree that is much greater than others of the same age. This requires at least six symptoms of either inattention or hyperactivity/impulsivity for those under 17 and at least five symptoms for those 17 years or older. The symptoms must be present in at least two settings (e.g., social, school, work, or home), and must directly interfere with or reduce quality of functioning. Additionally, several symptoms must have been present before age twelve.
Butoconazole (trade names Gynazole-1, Mycelex-3) is an imidazole antifungal used in gynecology. It is administered as a vaginal cream. Synthesis
Reaction of epichlorohydrin with 4-Chlorobenzyl magnesium bromide leads to 1-chloro-4-(4-chlorophenyl)butan-2-ol (3). Displacement with sodium imidazole, conversion of the secondary alcohol to the chloride (SOCl2), and displacement with 2,6-dichlorobenzenethiol concludes the synthesis of the antifungal butoconazole.
