Misdiagnosis of Asperger syndrome
Misdiagnosis of Asperger syndrome
Asperger syndrome can be a difficult diagnosis to make because there is no single test to detect it. An accurate diagnosis generally requires the evaluation of a team of professionals who are specialists in developmental disorders.
In addition, the symptoms of Asperger syndrome are similar to some symptoms of some other disorders. This can result in a delayed or missed diagnosis. For example, some people with Asperger syndrome may be misdiagnosed with "mild" form of autism disorder. However the two conditions are different and distinct disorders. Children and people with Asperger syndrome may also be misdiagnosed with other conditions with some similar behaviors, such as obsessive-compulsive disorder (OCD) or attention deficit hyperactivity disorder (ADHD)....more about Asperger syndrome »
Alternative diagnoses list for Asperger syndrome:
For a diagnosis of Asperger syndrome,
the following list of conditions
have been mentioned in sources
as possible alternative diagnoses
to consider during the diagnostic process for Asperger syndrome:
- Autism - Asperger syndrome is similar to autism with good language function.

Discussion of diagnosis/misdiagnosis of Asperger syndrome:
Some individuals who exhibit features of autism (a developmental
brain disorder characterized by impaired social interaction and
communication skills) but who have well-developed language skills may be
diagnosed with AS, although high-functioning autism differs from AS in
early language delay.

Common Misdiagnoses and Asperger syndrome
Mild worm infections undiagnosed in children: Human worm infestations, esp. threadworm, can be overlooked in some cases,
because it may cause only mild or even absent symptoms.
Although the most common symptoms are anal itch (or vaginal itch),
which are obvious in severe cases,
milder conditions may fail to be noticed in children.
In particular, it may interfere with the child's good night's sleep.
Threadworm is a condition to consider in children with symptoms such as bedwetting (enuresis),
difficulty sleeping, irritability, or other sleeping symptoms.
Visual inspection of the region can often see the threadworms, at night when they are active,
but they can also be missed this way, and multiple inspections can be warranted if worms are suspected.
See the introduction to threadworm.
Parental fears about toddler behavior often unfounded: There are many behaviors in infants and toddlers
that may give rise to a fear that the child has some form of mental health condition.
In particular, there is a loss of fear of autism or ADHD in parents.
However, parents should understand that the chances are higher that it's part of normal development,
and perhaps just a "cute behavior" rather than a serious condition.
Although parents should be vigilant about monitoring all aspects of their child's development and mental
health, they should also take care not to over-worry and miss out on some of the delights of parenthood.
For example, a young child that screams when you open his car door to take him out, then
makes you put him back into the car
to repeat it, so that he
can open the car door himself, is not necessarily showing signs of autism or OCD,
nor indeed any mental illness.
There is a small possibility that it's an abnormality (a chance that increases with age of the child),
but it's also the type of behavior seen in many normal children.
See the introduction to autism and introduction to ADHD.
Undiagnosed stroke leads to misdiagnosed aphasia: BBC News UK reported on a man who
had been institutionalized and treated for mental illness
because he suffered from sudden inability to speak.
This was initially misdiagnosed as a "nervous breakdown" and other mental conditions.
He was later diagnosed as having had a stroke, and suffering from aphasia (inability to speak),
a well-known complication of stroke (or other brain conditions).
Dementia may be a drug interaction: A common scenario in aged care is for
a patient to show mental decline to dementia.
Whereas this can, of course, occur due to various medical conditions,
such as a stroke or Alzheimer's disease,
it can also occur from a side effect or interaction between multiple drugs
that the elderly patient may be taking.
There are also various other possible causes of dementia.
Mesenteric adenitis misdiagnosed as appendicitis in children: Because appendicitis is one of the
more feared conditions for a child with abdominal pain, it can be over-diagnosed
(it can, of course, also fail to be diagnosed with fatal effect).
One of the most common misdiagnosed is for children with mesenteric adenitis
to be misdiagnosed as appendicitis.
Fortunately, thus misdiagnosis is usually less serious than the reverse failure to diagnose appendicitis.
Blood pressure cuffs misdiagnose hypertension in children: One known misdiagnosis issue
with hyperension, arises in relation to the simple equipment used to test blood pressure.
The "cuff" around the arm to measure blood pressure can simply be too small to accurately
test a child's blood pressure.
This can lead to an incorrect diagnosis of a child with hypertension.
The problem even has a name unofficially: "small cuff syndrome".
See misdiagnosis of hypertension.
Mild traumatic brain injury often remains undiagnosed: Although the symptoms
of severe brain injury are hard to miss,
it is less clear for milder injuries, or even those causing a mild concussion diagnosis.
The condition goes by the name of "mild traumatic brain injury" (MTBI).
MTBI symptoms can be mild, and can continue for days or weeks after the injury.
See the symptoms of MTBI or misdiagnosis of MTBI.
ADHD under-diagnosed in adults: Although the over-diagnoses of ADHD
in children is a well-known controversy, the reverse side related to adults.
Some adults can remain undiagnosed, and indeed the condition has usually been
overlooked throughout childhood.
There are as many as 8 million adults with ADHD in the USA (about 1 in 25 adults in the USA).
See misdiagnosis of ADHD or symptoms of ADHD.
MTBI misdiagnosed as balance problem: When a person has symptoms
such as vertigo or dizziness, a diagnosis of brain injury may go overlooked.
This is particularly true of mild traumatic brain injury (MTBI), for which the
symptoms are typically mild. The symptoms has also relate to a relatively
mild brain injury (e.g. fall), that could have occurred days or even weeks ago.
Vestibular dysfunction, causing vertigo-like symptoms, is a common complication
of mild brain injury.
See causes of dizziness, causes of vertigo, or misdiagnosis of MTBI.
Bipolar disorder misdiagosed as various conditions by primary physicians: Bipolar disorder (manic-depressive disorder)
often fails to be diagnosed correctly by primary care physicians.
Many patients with bipolar seek help from their physician, rather than a psychiatrist
See misdiagnosis of bipolar disorder.
Eating disorders under-diagnosed in men: The typical patient with
an eating disorder is female.
The result is that men with eating disorders often fail to be diagnosed or
have a delayed diagnosis.
See misdiagnosis of eating disorders or symptoms of eating disorders.
Depression undiagnosed in teenagers: Serious bouts of depression can be
undiagnosed in teenagers.
The "normal" moodiness of teenagers can cause severe medical depression
to be overlooked.
See misdiagnosis of depression or symptoms of depression.
Brain pressure condition often misdiagnosed as dementia: A condition
that results from an excessive pressure of CSF within the brain is often misdiagnosed.
It may be misdiagnosed as Parkinson's disease or dementia (such as Alzheimer's disease).
The condition is called "Normal Pressure Hydrocephalus" (NPH) and is caused by having
too much CSF, i.e. too much "fluid on the brain".
One study suggested that 1 in 20 diagnoses of dementia or Parkinson's disease were actually NPH.
See misdiagnosis of Alzheimer's disease or misdiagnosis of Parkinson's disease.
Post-concussive brain injury often misdiagnosed: A study found that soldiers who had
suffered a concussive injury in battle often were misdiagnosed on their return.
A variety of symptoms can occur in post-concussion syndrome and these were not being correctly
attributed to their concussion injury.
See introduction to concussion.
Children with migraine often misdiagnosed: A migraine often fails to be
correctly diagnosed in pediatric patients.
These patients are not the typical migraine sufferers, but migraines can also occur in children.
See misdiagnosis of migraine or introduction to migraine.
Undiagnosed anxiety disorders related to depression: Patients with depression (see symptoms of depression)
may also have undiagnosed anxiety disorders (see symptoms of anxiety disorders).
Failure to diagnose these anxiety disorders may worsen the depression.
See misdiagnosis of depression or misdiagnosis of anxiety disorders.
