Individuals with ADHD of the inattentive subtype tend to be disorganized, easily pulled off course, forgetful, and inattentive. They tend to be disorganized mentally and physically. They tend to make careless mistakes, and are not good at paying close attention to detail. They have difficulty organizing their work, setting priorities, planning out a strategy, and remembering to do all required tasks. They have difficulty organizing their things and tend to be sloppy. They have trouble keeping track of their belongings and forget where they have put them, in part because they rarely put things away. If multiple items are needed for an assignment or task, they will typically forget one or more. They have trouble keeping track of multiple things held in mind, which can make arithmetic calculation, reading, or abstract problem solving difficult.
Individuals with ADHD of the inattentive type also tend to have a hard time sustaining focused attention on a task or activity. They are quite poor at following through on something to completion. They tend to get bored with a task fairly quickly and often abandon a task unfinished, bouncing from one partially begun project to another. They may have a hard time keeping their mind on any one thing at a time. When doing homework or reading, they often find their minds wandering. Because focusing deliberate, conscious attention on completing a task is so arduous or aversive for individuals with the inattentive subtype of ADHD, they tend to try to avoid beginning a task, procrastinate, may forget to write an assignment down, forget to bring home the materials needed to complete an assignment, or lose materials needed for an assignment.
