Is it really possible for someone to have both ADHD and OCD?
With ADHD you may be forgetful, distracted, make careless mistakes, daydream, etc. With OCD, my impression is that you'd be very focused on details, a bit perfectionist, and generally meticulous. So how do they coexist, and what kind of behaviors do you attribute to each?
Seems to me that OCD is about putting a lot of focus and energy into unimportant things, something which Adhd-ers also can tend to do. The main difference is probably that OCD-ers are driven by anxiety rather than suffering from inability to prioritize tasks.
There are also those who believe that OCD and ADHD often occur together. This site on ADHD states, “It is not uncommon for someone to have both ADHD and OCD.” I find this statement baffling, as the basic symptoms of ADHD (listed below), in my opinion, seem to be in direct contrast to those of OCD:
Inattention: Having a short attention span and easily distracted. (Most people with OCD would love to be able to not pay attention to their thoughts.)
Impulsivity: Causes a person to do dangerous or unwise things without thinking about the consequences. (Those with OCD do the exact opposite. They play it safe and obsess about the consequences.)
Hyperactivity: Inappropriate or excessive activity. (Those with OCD often go out of their way to do what they feel is appropriate. Also, in Dan’s case, he often had very low energy as he was “wiped out” from struggling with his OCD.)
However I read here that:
Some research has suggested that OCD and Obsessive Compulsive Spectrum Disorders fall upon a compulsive-impulsive continuum. In other words there exists a gradient of disorders ranging from behavioral impulsivity to compulsivity. OCD appears to lie at one end of this spectrum, while ADHD exists at the other.
That reminds of this picture (taken from here):
Does this then mean that ADHD and OCD together is like mania and depression together? Is there a term for the former just like the latter has bipolar disorder?
There's someone in 1 who says
"ADHD makes my mind wander but then my OCD latches onto things I get so focused that nothing else exists."
and someone else who says
"The OCD part of is killing me on the inside on how messy my room is. I hate messy rooms.",
but there seem to be contesting comments such as
"Actual clinical OCD is so very far from the perfectionism you're describing."
"You are confusing Obsessive Compulsive Disorder with Obsessive Compulsive Personality Disorder...I don't know if OCPD and be comorbid with ADHD, but I agree that intuitively they don't seem compatible. OCD on the other hand is sometimes misdiagnosed as ADHD (and vice versa) as they both involve problems with impulse control."
There's another comment which might explain how ADHD and OCD are not opposites, but I'm not quite sure I understand (assuming it is right):
they aren't opposites. OCD is when you have strong anxious compulsions that you can't resist. ADHD is when you are unable to resist even weak impulses. They harm the patient in a devilishly sinergistic manner - let's take someone who already has difficulty resisting impulses, and give her compulsions to do useless things!
Is it right? What exactly does that mean?
