The referral gap is not proof of absence
ADHD is a neurodevelopmental condition involving developmentally inappropriate and impairing patterns of inattention and/or hyperactivity-impulsivity. Girls are less likely to be referred and diagnosed in childhood, yet the female-to-male difference narrows markedly in adulthood [1]. This pattern is consistent with under-recognition as well as possible differences in symptom expression. It should not be interpreted as evidence that every distracted or overwhelmed girl has ADHD.
Girls and women may show prominent inattention, disorganisation, forgetfulness, internal restlessness and emotional distress without the disruptive behaviour that often triggers a school referral. Compensatory effort can temporarily protect grades while exacting a high cost in exhaustion, anxiety or self-criticism. Symptoms may become harder to compensate for when academic, work, parenting or household demands increase [1][2].
- Quiet performance does not rule out substantial effort or impairment.
- A referral should consider function across settings, not a single classroom or workplace.
- Late recognition does not mean the condition began in adulthood.
A diagnosis is a structured clinical judgement
There is no single blood test, scan or app that diagnoses ADHD. Assessment should establish a developmental history, symptoms in more than one setting, functional impairment and alternative explanations. For children and adolescents, the AAP recommends obtaining information from parents, teachers, school personnel and mental health clinicians when appropriate, and screening for emotional, developmental and physical conditions that may coexist or mimic ADHD [3].
For an adult, records and recollections from childhood can help, but missing school reports should not automatically close the assessment. Clinicians should examine sleep disorders, anxiety, depression, trauma, substance use, thyroid disease, learning differences, autism, medication effects and major life stress. NICE advises that diagnosis be made by an appropriately trained specialist based on a full clinical and psychosocial assessment, developmental and psychiatric history, and observer reports, rather than rating scales alone [4].
- Rating scales organise evidence but do not replace an interview.
- Symptoms must cause meaningful impairment and not be better explained by another condition.
- Coexisting conditions can be present alongside ADHD and also need care.
The lifespan lens matters
Research on hormonal influences is growing, but it is not yet strong enough to support a universal hormone-based ADHD treatment algorithm. Some patients report changes around the menstrual cycle, pregnancy, postpartum or menopause. These experiences warrant careful tracking and clinical review, especially when sleep, mood, medication exposure or caregiving demands change at the same time. Association should not be presented as proof that one hormone level caused a symptom shift [2].
Pregnancy planning requires a personalised medication discussion. Decisions should consider current impairment, driving or occupational safety, prior response, other mental health conditions and the evolving evidence for a specific medicine in pregnancy or lactation. Stopping treatment without a plan may impair functioning, while continuing any medicine also requires a benefit-risk discussion. A reproductive and mental health clinician can coordinate this decision rather than relying on generic online advice.
- Track symptoms, sleep, cycle timing and functional impact before inferring a pattern.
- Review contraception and pregnancy intentions during routine medication care.
- Plan transitions between child, adult and perinatal services in advance.
Treatment should improve life, not only a score
Evidence-based care can include education, environmental adjustments, organisational strategies, school or workplace accommodations, behavioural support and medication. The appropriate combination depends on age, severity, goals, coexisting conditions and patient preference. NICE and AAP guidance supports regular monitoring of benefit, adverse effects, growth and cardiovascular parameters where relevant [3][4]. Treatment should be reviewed rather than continued automatically.
Good outcome measures are concrete: fewer missed medicines, safer driving, completing essential tasks, more reliable sleep routines, reduced academic crisis or less conflict around household responsibilities. Digital reminders and task tools can reduce cognitive load, but they are aids rather than treatments and can become another source of alerts. A care plan should select a small number of supports, assign ownership and review whether they actually improve function.
- Define two or three functional goals before changing treatment.
- Make accommodations specific to the barrier, such as written instructions or reduced distraction.
- Monitor benefits and harms with the same discipline.
What a gender-informed service changes
A gender-informed service does not apply a separate diagnostic standard to women. It improves case-finding by asking about less visible impairment, compensatory labour and internalising symptoms while still applying established criteria. It avoids assuming that good grades, employment or caregiving competence exclude ADHD. It also avoids turning common experiences such as stress or forgetfulness into a diagnosis without evidence [1][5].
Services can audit who is referred, assessed, diagnosed and retained in treatment by sex, age, race, language and socioeconomic context. They can train clinicians and educators to recognise inattentive presentations and develop referral routes that do not depend on disruptive behaviour. Most importantly, they can give people a coherent explanation without reducing every difficulty to ADHD. A rigorous formulation identifies what ADHD explains, what it does not and which supports are most likely to help.
- Ask how much hidden effort is required to maintain current performance.
- Include the patient's own account alongside observer information.
- Reassess the formulation when expected improvement does not occur.
What the evidence cannot yet answer
- Much ADHD research historically included more males, limiting precision about female-specific trajectories.
- Evidence on symptom changes across menstrual, pregnancy and menopausal transitions remains incomplete and heterogeneous.
- Observed diagnostic ratios combine biology, recognition, referral and access effects and cannot by themselves measure underdiagnosis.
Questions worth taking into care
- Which difficulties were present before age 12, and in which settings?
- What is the functional cost of compensating, even when performance looks adequate?
- Which sleep, mood, learning, trauma or medical conditions should also be assessed?
- What two outcomes would show that treatment is helping?
- How will pregnancy intentions or hormonal transitions be included in medication review?

This evidence synthesis is for general information. It does not diagnose a condition or replace care from a qualified health professional. Treatment choices depend on individual history, examination, local guidance and informed preference. Emergency or rapidly worsening symptoms need urgent local medical assessment.
