A question that keeps coming up

When a brain feels foggy, easily overwhelmed, and wired a little differently, it is hard to know which parts have been there all along and which were noticed only after ELC began. A small group of members answered a survey built around that experience. What follows are group-level patterns and some general science — offered as description, not as an answer about any one person.

If you only have energy for one page

Three group-level patterns

1. 1Almost everyone answered above the ADHD screener’s cut-off — but that largely reflects how closely the questionnaire’s attention items resemble the brain fog and fatigue of ELC. A high score, on its own, is not evidence of ADHD.
2. 2On the autism screener, the group fell roughly half above and half below the threshold. Scoring above a screening threshold is not an autism diagnosis or a lifelong profile.
3. 3Across the traits members endorsed, two broad patterns appear: some are traced back to childhood, and some were noticed only more recently. This distinction is descriptive — it cannot tell us why any trait is present.

Finding 01

The ADHD screener flags almost everyone — two cautions on reading it

The survey included a standard six-item adult ADHD screener. On paper the result looks dramatic: eleven of twelve answered above the positive cut-off. Taken at face value that would suggest an almost universal attention disorder — which is not something a screen alone can tell us.

Splitting the screener by item is where care is needed. It touches two different things: an attention & follow-through side (finishing tasks, staying organised, remembering, avoiding heavy thinking) and a hyperactive side (restlessness, feeling driven). Across the group, the first side is near the ceiling and the second is almost flat.

The first caution is overlap. Those four attention items closely resemble the cognitive fatigue and brain fog described in ME/CFS and Long COVID. In a group living with ELC, high marks on them are expected, and a high screening score can reflect the illness rather than a lifelong attention difference.

The second caution matters especially for a group of women, and it points the other way. It is tempting to read the near-empty hyperactive pole as a sign this is not “real” ADHD. That reading is a trap. In girls and women, ADHD far more often takes a quiet, inattentive form — with little of the visible restlessness the stereotype is built on — and it is precisely this quieter presentation that gets overlooked, so many reach adulthood undiagnosed, frequently labelled with anxiety or depression first (Hinshaw et al., 2021; Martin et al., 2024). A low hyperactivity score tells us little either way.

Which is one reason questionnaires like these ask about more than current symptoms — including whether anything was noticeable in childhood.

Finding 02

Childhood onset: one factor the questionnaire looks at, not a cause it can settle

The ADHD screener also asks, separately, whether attention, restlessness, or trouble staying organised were already noticeable before age 12. An early start is one of the features clinicians weigh. It is not something a questionnaire can confirm, and memories of childhood are imperfect — so this is a descriptive signal, not a diagnosis or a cause.

One general point is worth holding here. When you first notice a trait and when it actually began can be very different. An illness can hand someone the words for something that was there all along — so noticing a trait after ELC does not mean it started then. That is a reason to be gentle with quick conclusions, in either direction.

Finding 03

The autism screener divides the group

The second tool, a fourteen-item autism-spectrum screener, behaves differently from the ADHD one. Rather than catching almost everyone, it fell roughly evenly: six of twelve answered above the threshold. Scoring above a screening threshold does not establish an autism diagnosis or a lifelong profile — it is a prompt to learn more, nothing more.

What is useful here is a design detail: each trait is marked not just present or absent, but when it has been true — since childhood, only now, or only earlier in life. At the group level this is what the chart at the top of the page shows: both patterns are present, some traits long-standing and some noticed recently. That is a description of the group, not a statement about anyone in it.

The timing members reported about themselves and the trait-by-trait tags broadly lined up at the group level — which is what you would expect if the timing question is capturing something consistent. With a small, self-selected group this stays descriptive, and none of it points to a cause.

Finding 04

Sensory sensitivity is a common thread

One experience cut across the group. Raised sensory sensitivity — textures that feel offensive on the skin, a need to cover the ears or retreat from noise and light, having to withdraw to shut the senses down — was reported by nine of twelve, among those above and below the autism threshold alike.

It is offered here simply as a frequently shared, self-reported experience worth naming — not a measurement and not a sign of any condition. For many people, recognising sensory load as real, and giving it room, is a small relief in itself.

Something to take from this

Two questions worth sitting with

This survey does not hand anyone a label, and it cannot sort your experience for you. What it can offer is a gentler way to notice — two questions to sit with, for your own reflection rather than any diagnosis.

Hold both loosely. When you first noticed something and when it truly began are not the same, and only a clinician can help work out why any of it is there. The point is not to diagnose yourself — it is to meet your own experience with a little more clarity and care.
