Attention deficit hyperactivity disorder predominantly inattentive
Attention deficit hyperactivity disorder predominantly inattentive (ADHD-PI or ADHD-I), is one of the three presentations of attention deficit hyperactivity disorder (ADHD). In 1987–1994, there were no subtypes and thus it was not distinguished from hyperactive ADHD in the Diagnostic and Statistical Manual (DSM-III-R). The 'predominantly inattentive subtype' is similar to the other presentations of ADHD except that it is characterized primarily by problems with inattention or a deficit of sustained attention, such as procrastination, hesitation, and forgetfulness. It differs in having fewer or no typical symptoms of hyperactivity or impulsiveness. Lethargy and fatigue are sometimes reported, but ADHD-PI is a separate condition from the proposed cluster of symptoms known as sluggish cognitive tempo (SCT). Classification ADHD-PI is an attention-concentration deficit that has everything in common with other forms of ADHD except that it has fewer hyperactivity or impulsivity symptoms and has more directed attention fatigue symptoms. Signs and symptoms DSM-5 criteria The DSM-5 allows for diagnosis of the predominantly inattentive presentations of ADHD (ICD-10 code F90.0) if the individual presents six or more (five for adults) of the following symptoms of inattention for at least six months to a point that is disruptive and inappropriate for developmental level: Often does not give close attention to details or makes careless mistakes in schoolwork, work, or other activities. Often has trouble keeping attention on tasks or play activities. Often does not seem to listen when spoken to directly. Often does not follow instructions and fails to finish schoolwork, chores, or duties in the workplace (not due to oppositional behavior or failure to understand instructions). Often has trouble organizing activities. Often avoids, dislikes, or doesn't want to do things that take a lot of mental effort for a long period (such as schoolwork or homework). Often loses things needed for tasks and activities (e.g. toys, school assignments, pencils, books, or tools). Is often easily distracted. Is often forgetful in daily activities. An ADHD diagnosis is contingent upon the symptoms of impairment presenting themselves in two or more settings (e.g., at school or work and at home). There must also be clear evidence of clinically significant impairment in social, academic, or occupational functioning. Lastly, the symptoms must not occur exclusively during the course of schizophrenia or another psychotic disorder, and are not better accounted for by another mental disorder (e.g., mood disorder, anxiety disorder, dissociative disorder, personality disorder). Treatment Although ADHD has most often been treated with medication, medications do not cure ADHD. They are used solely to treat the symptoms associated with this disorder and the symptoms will come back once the medication stops. Medication Stimulants are typically formulated in fast and slow-acting as well as short and long-acting formulations. The fast-acting amphetamine mixed salts (Adderall) and its derivatives, with short and long-acting formulations bind to the trace amine associated receptor and triggers the release of dopamine into the synaptic cleft. They may have a better cardiovascular disease profile than methylphenidate and potentially better tolerated. The fast-acting methylphenidate (well known under the trade
