Understanding ADHD

It's one topic at a time. You can read it or click Listen: the phrase that sounds is color-coded.

What ADHD is

ADHD is a neurodevelopmental disorder. It consists of a persistent pattern of inattention, hyperactivity and impulsivity, or both. It begins in childhood and in many people continues into adulthood. It affects about 2.5 percent of adults and about 6 percent of children and adolescents. It's not laziness. It's not lack of intelligence. It's not bad manners. It's a different way of regulating attention, motivation and drive.

Inattention symptoms

Difficulty maintaining concentration on long or low-stimulation tasks. Careless mistakes happen. It's easy to get distracted by the outside and also by one's own thoughts. There are everyday forgetting: appointments, payments, calls, errands. Things often get lost. Getting organised, starting and finishing are hard. In adults, inattention is usually what persists most. Many people describe the opposite as well - being so focused on something that interests them that it is hard to stop.

Hyperactivity and impulsivity symptoms

Anxiety: moving hands or feet, standing up, needing to do something. Talking a lot or very fast. Interrupt or answer before the question is finished. Difficulty waiting your turn. Deciding quickly without thinking about the consequences: shopping, texting, sudden changes. In adults, hyperactivity is less noticeable on the outside. It's more like restlessness on the inside.

Emotions in ADHD

Intense, changeable emotions are very common in adult ADHD. In studies, about 7 out of 10 adults with ADHD report difficulty regulating their emotions. The most common are low tolerance for frustration, irritability, and rapid mood swings. The reaction is usually stronger than the situation demands, and then comes the guilt. It's not part of the official diagnostic criteria. It's considered an associated trait. Many people also describe a very high sensitivity to criticism and rejection.

How it is diagnosed

The diagnosis is made by a qualified healthcare professional after a thorough evaluation. There is no analysis, no imaging test, no test that can diagnose it on its own. Current symptoms, history from childhood and how they affect your life are assessed. Symptoms must have started before age 12. Adults are asked for at least five symptoms of inattention or five of hyperactivity and impulsivity. They must be present in two or more areas, for example at home and at work. Stress, sleep deprivation, anxiety, depression, or some other physical problem may resemble ADHD. This app provides information. It cannot be used for diagnosis.

ADHD in women

In girls and women, ADHD goes unnoticed more often. They tend to be inattentive, which attracts less attention in class. That's why many women are diagnosed as adults. Gender differences in diagnosis gradually equalize in adulthood.

Why it happens

There is no single cause. In most cases, many genetic and environmental factors are involved. Each weighs very little individually. Studies find small differences in brain structure and functioning. They're average differences between groups. They don't help diagnose a specific person. It's not your fault or your family's.

What often comes with it

Sleep problems affect up to 7 out of 10 adults with ADHD. Anxiety, depression and substance use problems are more common. There is also an increased risk of accidents and difficulties at school and work. Treatment of ADHD reduces several of these risks. If you notice any of these problems, talk to your health-care professional.

Which treatments work

Medication is the most effective treatment for the main symptoms. It is indicated and followed by a doctor. Treatments without medication have less effect on the symptoms. They help a lot with the problems that remain. Cognitive behavioral therapy adapted to ADHD reduces the main symptoms as well as emotional ones, such as anxiety and depression. Mindfulness can improve the main symptoms. Its effect on emotional well-being is less clear. Physical exercise shows small to moderate benefits, even after a single session. Usually, it's a combination of understanding ADHD, medication if necessary, therapy and changes in the environment.

Common myths

It's a childish thing. False. Many people still have adult symptoms. If you focus on what you like, you don't have ADHD. False. The problem is regulating attention, not lacking it. It's a recent fad. False. It's been described in medical texts since 1775. The medication creates addiction. Taken as directed by the doctor, it is associated with fewer drinking problems. The risk arises when used without medical supervision.

Tips for each difficulty

Choose the area that weighs the most on you today. Mark the pattern you're going to practice and it'll be kept in My plan.

Impulse

The impulse comes before the thought. The goal isn't to get rid of it. It's to gain a few seconds between the urge and the action.

The 10-minute rule. Before you buy, answer or decide, wait 10 minutes with the timer. If you still want to afterwards, decide.Stop, breathe, think. Say stop on the inside. Breathe slowly three times. Ask yourself what will happen in an hour if you do.24-hour shopping basket. Leave the shopping in the cart until tomorrow. Delete the cards stored in the online stores.Messages in the heat of the moment. Write the message in the notes, not the chat. Send it when you've lowered the intensity."If… then" plan. Prepare your answer before: if I feel like interrupting, then I write the idea down on paper.Put up barriers. Turn away what tempts you. The more steps there are between you and the behavior, the fewer impulses are fulfilled.

Guidelines are common techniques in cognitive behavioral therapy.

Managing emotions

In ADHD, emotions rise quickly and loudly. The most common are frustration, anger, shame, boredom, and burden. Also a very intense enthusiasm that then drops, and a lot of pain in the face of criticism.

Give it a name and a number. Say how you feel and how much, 0 to 10: angry, 7. Naming him helps you distance yourself.Calm your body first. Above 7 is not good reasoning. Breathe slowly, leave the room or walk for five minutes.Ask for a pause and come back. Say, "I can't talk right now, we'll get back to it in half an hour". And get back to it.Check the thought. Ask yourself: What proof do I have, what would I tell a friend, will it matter in a week?When criticised, check. Before you take it for granted, ask what they meant. A lot of times the tone you hear isn't what it was.Look after the basics. Sleepy, hungry, or after hours of not moving, it all goes off sooner.Talk to yourself as you would to a friend. I'm a disaster because this is hard for me and I'm learning it.

Phone distraction

Traits of ADHD, especially inattention, are associated with more problematic use of mobile phones. Apps are designed to grab your attention. It's not a lack of will. It works better to change the environment than to resist.

Out of sight. While you're working or studying, leave your cell phone in another room or in a drawer. Mouth down on the table isn't enough.Notifications to a minimum. It leaves only calls and messages from people. Remove the ads and balloons from the networks.A boring screen. Take the networks off the home screen and turn the phone to grayscale.Limits with a clear end. Use the time limit per app on your own phone. Have the password put in by someone you trust.Decide before unlocking. Say what you're taking it for: I'm going to check the weather. When you do, block it.No phone in bed. Load him out of the bedroom and use a regular alarm clock.Have a substitute. Boredom wants something. Have a book, notebook, or something for your hands.

Other distractions

Attention jumps to something new: a noise, a person, an open eyelid or your own ideas. It's about removing stimuli and giving ideas a place to wait.

Only one thing in sight. Leave on the table only what you need for this task.An idea parking lot. Keep a piece of paper nearby. When another idea comes up, write it down and carry on. Look at it when you finish.Control the noise. Try headphones, earplugs, or music without lyrics. It helps a lot of people.Short blocks. Work 15 to 25 minutes on a timer and rest 5. Use the tool.Work alongside someone. Doing the homework with someone beside you, even if each one does his own thing, helps to keep you going.One tab. Close everything not related to this task, including your email.Let others know your schedule. Tell whoever's with you when you don't want interruptions and when you do.

Addictions

People with ADHD are at greater risk for problems with alcohol, tobacco, cannabis, other drugs, and gambling. In studies, around 1 in 5 people in addiction treatment have ADHD. Impulsivity and the search for quick relief partly explain it. Treating ADHD is associated with fewer drinking problems.

Recognise the signs. You consume more than you wanted, you have trouble stopping, you use it to calm down or sleep, or it gets you into trouble and you keep going.Know your triggers. Note when the urges appear: emotion, place, time, and company.Let the wave pass. The urges go up, they peak and they come down on their own after a while. Set the timer and do something else in the meantime.Put distance between you. Don't keep it in the house. Block the betting sites. In Spain there is a register of self-prohibition of gambling.Find another stimulus. Intense exercise, music, a shower, a short challenge. The brain asks for activation, not that substance.Tell someone. Tell someone you trust. The secrecy keeps the problem.Seek professional help. If you are a regular user, tell your doctor or psychologist. Suddenly giving up alcohol or tranquilizers can be dangerous without supervision.

Procrastination

Starting is harder than doing. Boring, long or unclear homework is not stimulating enough.

A 2-minute first step. Open the document, write the title, that's all. Starting over changes the state.Break it down until it's not scary. It converts "making the statement" into steps that fit in 15 minutes.Set a day and time. There's no "then". Write down when and where you're going to do it.Immediate reward. Tie the homework to something enjoyable: a coffee, a song, ten minutes of rest.Commit to someone. Tell a person what you're going to do and what time you're going to show them.Don't wait until you feel like it. The urges come after you start, not before.

Guidelines are common techniques in cognitive behavioral therapy.

Organisation, time and forgetfulness

Working memory fills up early and time is misperceived. The solution is to get the information out of your head and put it where it can be seen.

One calendar. All appointments in the same place, with notice the day before and an hour before.One list. Write down all your homework in one place. Every morning, he picks three.Alarms with labels. Let the alarm tell you what to do: Get out of here and go to the doctor.A fixed place. Keys, wallet and cell phone always in the same tray by the door.Allow twice the time. If you think something's gonna take 20 minutes, book 40.Five minutes in the evening. Leave tomorrow's ready: clothes, bag and all three chores.A clock in sight. A big clock where you work helps you notice how time passes.

Restlessness and hyperactivity

The body wants movement, suppressing it takes attention. It's better to give it a planned exit.

Scheduled movement. Get up every 25 to 30 minutes. You stretch, you climb stairs, you drink water.Exercise before the hard part. An exercise session can improve your attention and control a little later.Busy hands. A ball, a rubber band, or scribbling while listening helps to keep your attention.More bearable meetings. Take notes, sit near the exit or ask to be shorter.Write it down instead of interrupting. Write down what you want to say and say it when the other person is finished.

Sleep

Up to 7 out of 10 adults with ADHD have poor sleep. Lack of sleep impairs attention, drive, and emotions.

Same time to get up. Every day, even on the weekends. It's what sleep commands most.A bedtime alarm. Set an alarm an hour before bed to start closing the day.Screens away. Put your cell phone out of the bedroom and turn off the lights.Light in the morning. Go outside or open the window as soon as you get up.Caffeine only in the morning. Avoid it from midday on.Empty your head onto paper. Before you go to bed, write down your concerns and concerns.See someone if it persists. If you have been sleeping poorly for weeks or are taking medication, talk to your doctor.

Relationships

Forgetfulness, interruptions and intense reactions wear down the people you live with. Explaining how you work and agreeing on supports changes things a lot.

Explain how you work. Tell me what's hard and what helps. It's not an excuse, it's information.Repeat what you heard. So you're asking me to... Avoid misunderstandings and show that you are listening.Agreements in sight. Tasks and dates on a blackboard or shared calendar.Repair soon. Apologize for the specifics, without justifying yourself, and say what you'll do differently.Pause signal. Make a deal to stop an argument and come back when it's quiet.
