A study from Nottingham Trent University warns that taking too many selfies could be a mental disorder.

Drs. Janarthanan Balakrishnan and Mark D. Griffiths, psychologists both, determined there are three types of habitual selfie takers: borderline, acute, and chronic -- and from there, the two developed the "Selfitis Behavior Scale."

The study was published in the International Journal of Mental Health and Addiction.

Long story short, they determined "Borderline" cases take a minimum of three self-shots a day, but don't post them to social media.

"Acute" cases differ because they actually post the pics they take.

Chronic sufferers, according to the study feel "compelled" to take and post selfies throughout the day. " Typically, those with the condition suffer from a lack of self-confidence and are seeking to 'fit in' with those around them, and may display symptoms similar to other potentially addictive behaviors,” Balakrishnan said.

The paper was apparently not without its detractors. It was shaded as an "academic selfie" by King’s College London Professor of Psychological Medicine Sir Simon Wessely, the Telegraph notes.
