Question and answer
Sinusitis is overdiagnosed: There is a tendency to give a diagnosis of sinusitis,
when the condition is really a harmless complication of another infection,
such as a common cold.
Whooping cough often undiagnosed: Although most children in the Western world have been
immunized against whooping cough (also called "pertussis"), this protection wears
off after about 15 years.
Thus, any teen or adult with a persistent cough may actually have whooping cough.
This is particularly dangerous for babies too young to be vaccinated,
and any un-vaccinated children.
Whooping cough can be fatal to an infant.
The cough symptoms of whooping cough is usually productive initially, but then
becomes a persistent dry cough, lasting up to 100 days.
Elderly grandparents may also be a reservoir of undiagnosed whooping cough.
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.
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.
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.
Pituitary conditions often undiagnosed cause of symptoms: There are a variety of symptoms
that can be caused by a pituitary disorder (see symptoms of pituitary disorders).
For example, fatigue, headache, weight gain, diabetes-like symptoms, and various other symptoms.
Pituitary tumors and other similar conditions are not as rare as physicians tend to believe.
See introduction to pituitary conditions.
