3PD is a new name for conditions formerly known as phobic
postural vertigo and chronic subjective dizziness. As the features, diagnostic criteria and treatment options
of 3PD have been refined over the past several years, 3PD will appear for the
first time in the next International Classification of Diseases, being released
in 2017.
What is 3PD? 3PD
is a non-vertiginous, waxing-waning dizziness and/or unsteadiness, persisting
for at least 3 months, with symptoms present at least 15 days per month, but
typically daily. 3PD often follows
a separate triggering event (vestibular neuritis, vestibular migraine, head
injury) that caused dizziness, vertigo or unsteadiness. With the anxiety or worry over an
underlying sinister cause (such as a brain tumor) of these symptoms or with the anticipation of having
another vestibular event, symptoms of 3PD develop.
What are the symptoms of 3PD? The symptoms of 3PD include dizziness and /or unsteadiness,
worse when upright, head or body in motion, and in visually busy environments,
becoming worse later in the day. Exacerbation
of symptoms in grocery or large stores, when reading, scrolling on the computer
or cell phone, and with exposure to complex patterns on carpeting, wallpaper or
clothing, is common. The dizziness
and/or unsteadiness become intrusive and those affected often report trouble
focusing/concentrating or “brain fog”.
How is 3PD treated?
Once other causes are ruled out with appropriate vestibular function
and/or other diagnostic testing, a combination of medications, such as
benzodiazepines and SSRIs (selective serotonin reuptake inhibitors) and
vestibular rehabilitation therapy is often effective. With significant underlying anxiety, cognitive behavioral
therapy may also be helpful.
