1.I struggle to begin or sustain tasks unless they are interesting, urgent, novel, or externally structured.
2.I lose track of time, belongings, appointments, or the steps needed to finish ordinary tasks.
3.I interrupt, act quickly, seek stimulation, or make decisions before I have considered the consequences.
4.Too much routine makes me restless, even though a lack of structure makes daily life harder.
5.I consciously work out social rules, implied meanings, facial expressions, or the right moment to speak.
6.I rehearse conversations or rely on scripts because spontaneous social interaction is difficult to navigate.
7.Sounds, lighting, textures, smells, crowds, or physical sensations affect me more intensely than other people expect.
8.Unexpected changes or interruptions can leave me distressed, disoriented, or unable to switch plans.
9.I become deeply absorbed in particular topics, systems, collections, or activities and return to them for comfort or mastery.
10.My preferred way of doing something can feel important even when others see the difference as minor.
11.I crave novelty and predictability at the same time, creating a repeated conflict between boredom and overwhelm.
12.I can appear capable for a period, then abruptly lose capacity after sustained focus, social effort, or sensory demands.

How to read the dimension scores

Higher attention, activation, impulsivity, and stimulation scores may point toward ADHD-related experiences. Higher social communication, sensory, sameness, and focused-interest scores may point toward autistic experiences. Elevated scores across both groups can be consistent with an AuDHD profile, but they cannot establish it.

Why autism and ADHD are easy to confuse

Both can involve executive dysfunction, emotional regulation difficulties, social problems, intense focus, sleep disruption, and overwhelm. The reasons can differ: losing a conversation because attention shifted is different from struggling to infer its social meaning, although both can happen together.
