If you or your child has both conditions, it is best to treat the OCD first. Obsessive-compulsive symptoms can manifest through ADHD. In addition, the hallmark of OCD is performance of repetitive, precise, and accurately timed rituals, which requires extremely Adult add and ocd attention.

ADHD, which adds a hyperactive component to ADD, is a legitimate brain disorder that typically occurs as a result of neurological dysfunction in the prefrontal cortex.

  • Fidgety distractibility is a common sign of ADHD.
  • One-third of adults with OCD had the disorder as a child.
  • Because he desperately wanted to be well enough to return to school in the fall, Dan spent his summer at a world-renowned residential treatment program for OCD.

When you have ADHD, one of the issues is that your brain has a low level of a chemical called dopamine. When you have OCD, one of the issues is that your brain has too much of a chemical called serotonin. Sometimes people with ADHD tend to have what look like compulsive tendencies. This is because we've learned to overcompensate for difficulties that we've experienced with distraction, disorganization and inattention. For example, when I shut the trunk of my car, I look to make sure my keys are in my hand.

I also check that the stove is turned off after I've been using it and about to leave the house. I don't do those things because I have a compulsion; I have tendency to misplace my keys, so I want to make sure that I know that they're with me and in my hand before I shut the trunk of the car, and I check the oven because I've left it on before when I was at home. So there are some things that people with ADHD do to compensate for having problems with attention, focusing and forgetfulness.

In regards to organization, I need to have a really clean workspace in order to work effectively. I went from having a large desk to a small desk just to eliminate the space I would use to stack papers. I'm not alone; a lot of people with ADHD need to have things really clean and organized in order to focus. The issue is that we can't always keep it clean. To combat this, I spend 15 minutes each night just picking up as much stuff in the house as I can.

That seems to keep things pretty organized and prevents clutter from building up. I also hired an assistant to come to my house a few hours a week. She helps keep me organized by going through papers with me, and she shows me new ways to stay organized that I can actually stick to.

I feel overwhelmed and have to step back for a few minutes to give my brain a rest. Having those experiences reminds me that having a nice, clean workspace where everything's organized helps me focus and have a greater feeling of well-being. Stimulant medication for ADHD also helps me stay organized. It also helps me stay focused in environments that are not as organized.

It helps me filter out distractions, such as being surrounded by piles of papers or being in a chaotic environment. Being organized is not something that came naturally to me; I had to learn how to do it. And I still need help in order to maintain organization. When you have compulsions, that means that you have a certain ritual or have to do things a certain way. You may also have something called "magical thinking" where you feel that you have to do something "just so" or else something bad will happen.

Compulsions are like a scratch you just have to itch. Not being able to follow through with your ritual causes you great distress. You continue to focus on that ritual during the day, you can't stop thinking about it, and you just don't "feel right" until you can do the ritual again.

You never really get relief from that feeling of anxiety. When you have OCD, you may also have obsessions -- images, thoughts or ideas in your head that won't go away. The content of these obsessive thoughts can be nonsensical, scary or both. You may have an uncontrollable urge to repeat a word or phrase over and over in your head. Disturbing images may pop into your head, images that you just feel like you don't have control over. As you can see, when you have OCD symptoms, it's different from just overcompensating for being disorganized, which is the case with ADHD.

When you have ADHD, forgetting to check your oven before you leave the house may bother you a little, but you usually can talk yourself down from it and get on with your day. With OCD, however, not doing a checking ritual causes you great distress, to the point where you can have difficulties functioning for the rest of the day.

So again, when you have ADHD, you may check things and have a need for a clean workspace, but it's because you are compensating for your tendency to be forgetful and disorganized.

OCD and ADHD Similarities Can Cause Misdiagnosis

Neuropsychological and neuroimaging studies suggest that partly similar executive functions are affected in both disorders. The deficits in the corresponding brain networks may be responsible for the perseverative, compulsive symptoms in OCD but also for the disinhibited and impulsive symptoms characterizing ADHD.

This article reviews the current literature of neuroimaging, neurochemical circuitry, neuropsychological and genetic findings considering similarities as well as differences between OCD and ADHD. Obsessive compulsive disorders OCD are typically characterized by the presence of recurrent, intrusive, and disturbing thoughts obsessions which often elicit anxiety or emotional stress followed by repetitive stereotypic behaviour or thoughts compulsions in order to neutralize the negative affects American Psychiatric Association According to ICD diagnostic classification, OCD consists of recurrent and persistent thoughts, behavioural patterns, ideas, and impulses that impose themselves against internal resistance, experienced by the patient as excessive and distressing.

The presence of insight is of clinical importance because insight not only correlates with age but also with severity and positive therapy response Walitza Clinicians also have to specify whether the patient has a current or past history of a tic disorder, this will be classified as a tic-related obsessive compulsive disorder American Psychiatric Association ; Thomsen ; Walitza Delorme et al.

The symptoms vary depending on context, the higher the structure of the context e. According to DSM-5 criteria, ADHD is now classified as a neurodevelopmental disorder, which is a group of conditions with onset in the developmental period. These disorders also including autism spectrum disorders and learning disorders typically manifest in early development, often before the child enters grade school, and are characterized by developmental deficits that produce impairments of a broad range of social functioning American Psychiatric Association Sheppard et al.

Masi et al. This article aims to summarize and compare findings of structural and functional abnormalities, neuropsychological aspects, biochemical and genetic studies on OCD and ADHD.

Despite the high comorbidity of both disorders, only very few studies have investigated both together or have directly compared both within the same study.

Extensive neuroimaging literature exists on the comparison of either disorders with matched healthy controls, and a variety of methods have been used to assess brain structure, metabolism, and the spatial and temporal organization of brain networks.

The timing of information processing is commonly studied with brain imaging methods that exhibit a high temporal resolution in millisecond time range, such as electroencephalography EEG or alternatively by magnetoencephalography. Details about brain structure and the spatial activation pattern are best assessed by functional magnetic resonance imaging or positron emission tomography PET.

We focused on similarities and differences of affected brain regions reported across these patient groups and specifically point to meta-analytic studies and their findings. There is considerable evidence for structural differences in the brains of ADHD patients when compared to age-matched healthy controls.

Regarding age, it has been shown that patients with ADHD show a regional delay in the maturation of cortical thickness, especially in regions responsible for cognitive control such as attention, working memory, inhibition and evaluation of reward contingencies in the prefrontal cortex Shaw et al.

The authors thus suggested that the abnormal development of cognitive control and motor areas may drive the poor control of motor activity Shaw et al. They emphasize the reduced volume of the basal ganglia, especially the lentiform nucleus globus pallidus and putamen Ellison-Wright et al. Older studies were inconsistent on whether this structure showed enlarged Baxter et al. A review Piras et al.

Besides alterations in basal ganglia, the meta-analyses of structural differences between OCD patients and healthy controls also detected reduced grey matter in the frontal eye fields, the dorsolateral prefrontal cortex, and the medial frontal cortex, including the anterior cingulate cortex ACC Radua and Mataix-Cols , the left and right orbito-frontal cortex OFC , and the supramarginal gyrus Rotge et al.

An overview of the regions with altered grey matter volumes in patients, as reported in the above-mentioned meta-analyses Ellison-Wright et al. Nicely visible are the differences in the volume of the basal ganglia in ADHD reduced volume: light blue and OCD increased volume: yellow as compared to controls. The structural abnormalities thus nicely converge with the neurobiological models, suggesting a failure of cortico-striato-thalamico-cortical CST circuit function in ADHD and OCD patients van den Heuvel et al.

Apart from clear support for abnormal activation in orbito-fronto-striatal regions, lateral frontal, anterior cingulate, middle occipital, and parietal cortices, the cerebellum also exhibited altered activation in cognitive tasks Menzies et al. The alterations in the activation pattern of ADHD differed between children and adults as shown in a recent meta-analysis.

Both adults and children yielded hypoactivation in fronto-parietal executive function networks that have been related to the well-known deficiencies in performing goal-directed executive processes and hyperactivation in the default network, suggesting a faulty interregulation between the networks activated during tasks and the default network Cortese et al.

Further alterations in activation have been detected in the ventral attention and the somatomotor networks in children and in the visual and dorsal attention systems in adults Cortese et al. The ACC has an important role in attentional and emotional processes Bush et al. The characteristic overactivation of this brain structure in OCD patients points to excessive activity in the action monitoring system when processing errors or correct responses in high-conflict trials Maltby et al.

The high time resolution of ERPs allows one to better disentangle conflict-related from actual error-related effects through response-locked averaging.

Holroyd and Coles suggested that the Ne emerges when a phasic error signal originating from the mesolimbic dopamine system is processed in the ACC in order to modify performance and update behaviour Holroyd and Coles A very recent meta-analysis of the Ne in adolescent and adult patients with ADHD clearly supported previous findings of Ne attenuation Geburek et al.

Anterior cingulate cortex activity has not only been related to performance monitoring and conflict anticipation Sohn et al. Thus, ACC overactivity in OCD may, in addition to excessive performance monitoring, also indicate a failure in the inhibition of prepotent responses in OCD patients causing the repetitive behaviour of compulsions Maltby et al.

Hypoactivation and corresponding deficient inhibition in ADHD seem responsible for inappropriate higher-order motor control mechanisms Rubia et al. On the other hand, and probably depending on the task, hyperactivation can occur in similar cortical and subcortical structures of ADHD patients Durston et al. Regarding the N2, the findings in OCD patients are inconsistent: depending on the task, authors reported comparable Di Russo et al.

The N2, generated in the caudal region of the ACC, precedes the actual motor response during conflicting trials van Veen and Carter b. Even though the N2 has traditionally been associated with inhibitory processes, the modulation of its amplitude by conflict level indicated that the N2 primarily reflects conflict processing rather than motor inhibition Donkers and van Boxtel ; Enriquez-Geppert et al. Accordingly, a recent study showed that the conflict-induced amplitude increase in the N2 was significantly reduced in children with ADHD.

The subsequent P3 has been associated with phasic inhibitory motor control mechanisms emerging from the right frontal cortex Strik et al. The Nogo P3 typically shows an anteriorisation Nogo anteriorisation of its central positivity in contrast to Go trials Fallgatter and Strik which has been related to ACC activity and prefrontal response control Fallgatter et al.

Both children and adults with ADHD showed reduced amplitudes and diminished Nogo anteriorisation in the narrow time window preceding actual response inhibition in the P3 Fallgatter et al. A direct comparison of functional activation between ADHD and OCD patients is only available from a paediatric sample and for tasks concentrating on executive functions.

The group of Rubia examined interference inhibition, selective attention Rubia et al. Common dysfunction in paediatric patients with ADHD or OCD as compared to controls emerged as hypoactivation in mesial frontal areas: reduced activity in patients was found in the right orbito-frontal cortex and ACC for successful inhibition, in the left medial frontal cortex and ACC for failed inhibition, and finally in bilateral inferior frontal and insular cortices extending also to the left premotor cortex, right superior temporal areas, and putamen for cognitive switching processes Rubia et al.

Further interference inhibition and selective attention in a modified Simon task was associated with reduced activity in supplementary motor areas, the ACC and superior parietal cortices in both patient groups Rubia et al.

Disorder-specific hypoactivation was predominantly found for ADHD patients and again was condition and task specific: activation in the left putamen, caudate, cingulate, and parietal cortex was reduced as compared to healthy controls and OCD patients during cognitive switching Rubia et al.

The pattern of functional deficits in the basal ganglia thus corresponds to the consistent structural abnormalities reported for ADHD Ellison-Wright et al.

Disorder-specific alterations in brain activation of children with OCD were less pronounced. They differed from healthy controls and ADHD patients only in the oddball condition by showing reduced activation in the right superior and middle frontal gyri of the dorsolateral prefrontal cortex Rubia et al. In summary, deficits in the cortico-striato-thalamic circuits responsible for cognitive control and performance monitoring processes are characterized in both neuropsychiatric conditions: ADHD and OCD.

According to the nature of their symptoms situated at the opposite ends of the impulsive—compulsive spectrum, they either exhibit hypo- or hyperactivation of affected brain structures such as basal ganglia or the mesial frontal cortex Rubia et al.

Several studies report problems in visuo-spatial working memory Moritz et al. Deficits in motor and processing speed have also been reported Burdick et al. Only few studies have investigated neuropsychological performances in paediatric OCD, which partly replicate findings from OCD in adults on impaired inhibition Rosenberg et al. Neuropsychological deficits have also been found in remitted OCD Chamberlain et al. In ADHD research, a large number of studies have investigated neuropsychological functioning both in children and adults.

Meta-analyses report consistent deficits in the domains of response inhibition, vigilance, planning, and working memory Huang-Pollock et al. Metacognition is impaired in OCD and the cognitive style of patients with OCD is marked by doubts about their own performance Hermans et al.

Children with ADHD show impaired error monitoring and a lack of characteristic post-error slowing in inhibitory response tasks Schachar et al. As mentioned above, in electrophysiological studies, this impairment is reflected by a diminished amplitude of the error-related negativity Albrecht et al.

In OCD patients, in contrast, error-related negativity is enhanced Endrass et al. However, a recent study based on large groups indicates that impaired decision-making might be a key feature in OCD da Rocha et al.

It has been hypothesized that impaired learning from feedback Nielen et al. However, learning from feedback seems intact when it leads to the avoidance of negative consequences Endrass et al. Vloet et al. Subjects with OCD showed impaired implicit learning. These authors view executive function deficits in OCD as an epiphenomenon caused by the overflow of intrusive thoughts.

According to their executive overload model, cognitive deficits in OCD patients result from the attempt to gain control over automatic processes in order to reduce impulsive behaviour and lapses of attention. This leads to increased consummation of cognitive resources and in return to diminished effective control. In ADHD as in OCD, apparent inconsistencies in neuropsychological findings have been explained by the existence of disorder-specific subgroups with differing neuropsychological key deficits.

In OCD, the paradox of concurrent findings of diminished inhibitory control and slow responding has been related to different symptom dimensions, e.

Differential neuropsychological profiles have been described e. Similarly, contradicting neuropsychological findings in ADHD have been explained by different neurobiological origins and the ensuing heterogeneity of neuropsychological symptoms.

Recently, impaired time processing has been suggested as a possible third pathway Sonuga-Barke et al. Comorbidity may attenuate or enhance neuropsychological symptoms. Neuropsychological deficits have been found to be less pronounced in OCD with comorbid tics or Tourette disorder Chang et al. Neurotransmitter interactions and homeostasis are essential features of normal behaviour.

The seminal work of Albin et al. The CST circuitry and its subregional connections play a major role; hyperkinetic disturbances are based on reduced stimulation of the substantia nigra pars reticulata and the medial globus pallidus by the subthalamic nucleus NST. This can be caused by a disturbance of the NST ballism or via reduced striatal inhibition of the lateral globus pallidus choreatic movement Reiner et al.

In both cases, the result is disinhibition of the thalamus which in consequence leads to reduced feedback on cortical areas Crossman et al. Sensory impulses may be causal for the hyperkinetic movements. Healthy individuals are able to suppress such reactions Albin et al. Striatal nerve cells, which are sensitive for such sensory stimuli Crutcher and DeLong , seem to play a key role in uncontrolled sensory inputs Paloyelis et al. Such work has been reviewed in detail by Berger and Riederer , Mehler-Wex et al.

There is a structural abnormality in children with ADHD supporting the hypothesis of a nigro-striatal defect Romanos et al. Additionally, impulsivity, attention deficit, and mood changes seem to be related to modulating circuits involving other brain areas. Not only dopaminergic drugs can influence impulsivity and compulsive behaviour. Such data clearly demonstrates noradrenergic neurotransmitter interactions within mood circuitries.

These observations by Gallagher et al. The D4 receptor is enriched in the prefrontal cortex and thus has been implemented in mood disorders.
