A doctor has highlighted the subtle signs he often observes in adults with Attention Deficit Hyperactivity Disorder (ADHD). These are traits people with ADHD may recognise in themselves but that are rarely discussed publicly. A consultant psychiatrist has highlighted subtle signs of Attention Deficit Hyperactivity Disorder (ADHD) that often go unnoticed. Dr. Ali Ajaz, who shares advice with over 97,600 TikTok followers, recently outlined six “hidden features” of ADHD that aren’t as widely discussed as the more familiar symptoms. These lesser-known traits can help adults recognise the condition in themselves or others.What Is ADHD?Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that begins in childhood and often continues into adulthood. It involves persistent challenges with attention, hyperactivity, and impulsive behaviour. Children with ADHD may struggle in school, face difficulties in relationships, and experience low self-esteem. While symptoms can lessen over time, many continue to experience them as adults. Although there’s no cure, early diagnosis and a combination of medication, behavioural therapy, and education can significantly improve daily functioning and long-term outcomes.ADHD SymptomsThe main symptoms of Attention-Deficit/Hyperactivity Disorder (ADHD) include difficulty focusing, impulsive behaviour, and excessive activity levels. Signs of the condition usually appear before the age of 12 and, in some cases, can be noticed as early as age 3. The symptoms can range from mild to severe and must be present in more than one environment, such as home, school, or work to confirm a diagnosis. These behaviours often interfere with growth, learning, and everyday functioning and may persist into adulthood.ADHD is diagnosed more frequently in boys than in girls, though it can look different between the two. Boys are often more visibly hyperactive, while girls may show quieter patterns of inattention that can easily go unnoticed.There are three main types of ADHD:1. Predominantly Inattentive Type:Individuals mainly struggle with concentration, organisation, and completing tasks. They may appear forgetful or easily distracted2. Predominantly Hyperactive-Impulsive Type:This form involves restlessness, excessive movement, and impulsive decisions. The person may act without considering the consequences or have difficulty sitting still.3. Combined Type:This type includes a mix of inattentive and hyperactive-impulsive symptoms, meeting the criteria for both categories.Hidden Signs of Adult ADHDDr Ali Ajaz in his recent tiktok video talked about less than the 'classic' signs of the condition.According to the doctor, people with ADHD often show certain behaviours that are rarely discussed but are quite common. One of them is hyperfocus which is getting so engrossed in something that they completely lose track of time. While this can be an advantage in some situations, it often causes them to ignore other responsibilities or personal needs.Another sign is having an unusually high or low sex drive. For some, sex serves as a form of stimulation or a way to release tension, while for others, it feels like too much effort and concentration, leading to disinterest.He also mentioned binge eating, explaining that the ADHD brain constantly seeks stimulation, and food becomes an easy source of instant gratification. Finally, he pointed out rejection sensitivity, where even mild criticism can feel deeply hurtful, often resulting in overthinking and emotional withdrawal.The doctor went on to explain that low self-esteem and self-doubt are also very common among people with ADHD. These feelings often come from years of struggling with symptoms, either being told they are not trying hard enough or putting in their best effort but still falling short of expectations. Over time, this combination can deeply affect confidence and self-worth.Lastly, he mentioned chronic gut problems such as bloating, pain, constipation, or diarrhoea. These issues, he said, are closely linked to the gut-brain connection, as ADHD brains often show signs of inflammation. Much of this inflammation, he explained, comes from diet and eating patterns.
