What is ADHD?
Attention deficit hyperactivity disorder (ADHD) is a lifelong condition that affects attention, activity levels and impulse control. It reflects differences in how the brain develops and works, particularly in the systems that manage focus, motivation and planning (often called “executive function”).
ADHD isn’t an illness, it isn’t caused by bad parenting, and it isn’t a lack of effort or intelligence. It’s often diagnosed alongside autism, a specific learning difference, anxiety or depression.
Around 2 to 3% of adults worldwide are thought to have ADHD, according to World Health Organization surveys in many countries, and some national estimates are higher. Many weren’t diagnosed as children, particularly women and people whose difficulties were put down to behaviour or “not trying”.
The three presentations
Predominantly inattentive
- Easily distracted, or lost in thought
- Struggles to finish tasks or follow long instructions
- Loses track of time, tools and paperwork
- Often overlooked, especially in women
Predominantly hyperactive-impulsive
- Restless, fidgety, finds stillness hard
- Talks a lot, interrupts, acts on impulse
- Craves activity and new experiences
- Often more visible, and diagnosed earlier
Many people have a mix of both, called the combined presentation. All three are ADHD.
What about ADD?
“Attention deficit disorder” (ADD) is an older name. Since 1987 the official term has been ADHD, including for people who aren’t noticeably hyperactive. Some people still use ADD to describe the inattentive presentation, and that’s fine.
How ADHD can affect people
ADHD affects everyone differently. Some people manage it well with their own strategies; others find medication makes a big difference. Common experiences include:
- restlessness, or difficulty staying still for long periods
- difficulty with boredom and repetitive tasks
- difficulty organising, prioritising and managing time (“time blindness”)
- forgetting appointments, or losing small items
- acting or speaking on impulse
- putting things off until the last minute, then working intensely
- strong emotions that rise quickly
- low self-esteem, often after years of being told to “try harder”
Hyperfocus
Many people with ADHD can focus intensely, sometimes for hours, on a task that captures their interest. It can be a real strength, as long as they don’t lose track of everything else.
The strengths of ADHD
With the right support, ADHD can be a real advantage, especially in fast-moving, practical or people-focused roles.
- Creative
- thinking outside the box and solving problems
- Energetic
- drive, enthusiasm and stamina
- Resilient
- bouncing back and adapting quickly
- Calm in a crisis
- clear thinking when everything changes at once
In a crisis, many people with ADHD become calm and focused. A fast-changing situation is a challenge to solve, and their energy and creativity come into their own.
These strengths suit roles such as:
- marine emergency response and crisis management
- engineering officer roles, especially where a hands-on approach is needed
- VTS operators in busy ports
- passenger and hospitality roles
- recruitment, crewing and HR
- project management and sales
ADHD at sea
Often suits people with ADHD
- Busy, varied, hands-on work
- Emergencies and fast-changing situations
- Clear, short-term goals
- Working with people
Can be harder
- Long, quiet night watches
- Repetitive tasks and long periods of low stimulation
- Dense paperwork and long written procedures
- Rigid schedules with little movement
Clear checklists, closed-loop communication, varied duties, short regular check-ins and visual reminders all help. See our guide to clear communication at sea.
Medication
Many adults with ADHD take prescribed medication, such as stimulants (for example methylphenidate or lisdexamfetamine) or non-stimulants (for example atomoxetine). Medication doesn’t change who someone is; for many people it makes focus and organisation much easier.
Some ADHD medicines are controlled drugs. That matters for seafarers in two ways:
Your medical certificate
Your approved doctor will want to know what you take, how long you have been stable on it, and whether it has side effects that could affect safety. See our guide to medical fitness at sea.
Travelling and joining ships
Rules on carrying controlled medicines vary widely between countries. Some require permits or letters in advance; a few ban some ADHD medicines altogether. Check every country on your route using our ADHD medication map.
Supply at sea
Plan how you will get enough medication for your whole contract, and keep it in its original packaging with your prescription.
Common myths
“ADHD only affects boys.” Wrong. ADHD affects people of every gender, and many women are diagnosed as adults.
“People with ADHD are lazy and just need to try harder.” Incorrect. ADHD isn’t a lack of motivation. Telling someone with ADHD to “focus harder” is like telling someone with poor eyesight to “look harder”.
“People with ADHD can’t get a seafarer medical.” Incorrect. Many people with ADHD hold unrestricted seafarer medical certificates. Fitness is assessed individually.
“Everyone’s a bit ADHD.” Everyone gets distracted sometimes. ADHD is a lifelong difference that affects many areas of someone’s life.
“ADHD is caused by bad parenting, sugar or screens.” False. ADHD is a neurodevelopmental difference, and is strongly inherited.
“ADHD can be cured.” No. ADHD is lifelong, though medication, strategies and the right environment can make a big difference.
