What are the symptoms of overstimulation? “Common symptoms of overstimulation include irritability, stress, agitation, insomnia, loss of focus, overwhelming feelings and thoughts, and anxiety,” Hoang says. “It may be difficult to block out or ignore sensory input. One may experience uncomfortable feelings in the body.”
Extreme discomfort.
Some people who are overstimulated may experience extreme emotional or even physical discomfort. They may display extreme irritability, anxiety, or fear. Some may voice their discomfort by crying or throwing tantrums. Or, they may even show aggression.
What Does Overstimulation Feel Like? Overstimulation is a state of feeling overwhelmed by the situation you are in. This might take the form of physical or emotional discomfort and feeling like your brain is frozen or you're unable to think or process anything that's happening.
Understimulation is when there is not enough sensory input or feelings, so the person may stim their own stimulation of their senses. Overstimulation is where there are too many sensory inputs, and the person may stim to control the overwhelmed feeling they have.
Overstimulation is a daily reality for many people with ADHD. We feel too much — physically and emotionally. We struggle with emotional regulation, impulsivity, and big feelings. Many of us also experience sensory sensitivities, reacting strongly to sights, tastes, smell, and more.
Research suggests that people with ADHD produce less dopamine from positive stimulation than neurotypicals1, which can lead to feeling understimulated in situations that others are typically comfortable in.
Differences in emotions in people with ADHD can lead to 'shutdowns', where someone is so overwhelmed with emotions that they space out, may find it hard to speak or move and may struggle to articulate what they are feeling until they can process their emotions.
ADHD meltdowns are sudden outbursts of frustration and anger that seem to come out of nowhere. If your child is struggling to control their emotions, there are ways to help them. For children with attention deficit hyperactivity disorder (ADHD), impulsivity can present in many ways.
Symptoms of Sensory Overload in ADHD
Headaches, dizziness, or light-headedness. Feeling ill, faint, or nauseous. Increased anxiety and stress. Irritability and agitation.
What is a sensory meltdown? Sensory meltdowns are what I consider to be extreme temper tantrums that have a sensory trigger to them. These typically involve extreme aggressive behaviors (head banging, hand biting, scratching or pushing others), and require a lot of assistance to recover.
Often, it can feel like you're hypersensitive to touch and have to back off, or you may not feel much of anything. Don't worry too much, though — and don't believe the vibrators-are-bad rumors: overstimulation is normal and typically temporary, usually lasting just a couple of minutes.
Rather, it's a sense of overwhelm or overstimulation that does not feel manageable in the moment. People with this condition typically experience different triggers and symptoms. Some signs of a sensory overload reaction can include: Anxiety and an inability to relax. Irritability.
Inattentiveness and difficulty concentrating may cause fatigue, especially among students and full-time employees working long days. Distractibility and poor focus can cause people with ADHD to quickly lose interest in activities or objects that once gave them pleasure as well.
Adults with ADHD may find it difficult to focus and prioritize, leading to missed deadlines and forgotten meetings or social plans. The inability to control impulses can range from impatience waiting in line or driving in traffic to mood swings and outbursts of anger.
ADHD burnout is often something a little deeper. It refers to the cycle of overcommitting and overextending that leads to fatigue in people with ADHD. It involves taking on too many tasks and commitments, and then the subsequent exhaustion that happens when we're unable to fulfill all of our obligations.
High-functioning ADHD could mean: you experience severe symptoms but have developed “work arounds” to carry on with daily tasks and responsibilities. your symptoms are mild, and you're able to function with minimal impairment. symptoms are greatly impairing in some areas but you're highly functional in others.
Atypical Presentation of ADHD Symptoms:
Impaired sense of time (loses track of time, often late, hates waiting, avoids doing homework, etc.) Sleep disturbances (has trouble with sleep initiation, sleep deprived, can't wake up easily, etc.)
The mind of a person with ADHD is full of the minutiae of life (“Where are my keys?” “Where did I park the car?”), so there is little room left for new thoughts and memories. Something has to be discarded or forgotten to make room for new information. Often the information individuals with ADHD need is in their memory…
Because children and adults with ADHD struggle with focusing, organizing tasks, and feeling restless, they might experience sadness, guilt, irritability, low self-confidence and helplessness. In some cases, these symptoms can signal depression.
What does sensory overload feel like in ADHD? When a person with ADHD experiences sensory overload, they can become so fixated on a certain sensation, they're often unable to turn their attention away from the stimuli or focus on other tasks. This can make it difficult to meet expectations at school or work.
