Doctors may soon be able to diagnose Alzheimer's over the phone just by listening to the way patients talk.

Researcher Sona Patel of Seton Hall University is conducting a study on how Alzheimer's impacts the voice, and she is developing ways to detect vocal differences between the voices of normal aging adults and those with Alzheimer's disease.

Scientists have already proven that the voice can be used to detect Parkinson's disease with 99 percent accuracy because of revealing symptoms such as a vocal tremor and breathy speech.

"You react to stimuli with your voice automatically, without even realizing it," she told the Express.

"Now, the question is if we can use voices to indicate other neurological disorders."

Patel conducts research by recording brain activity via brain scans while patients perform vocal activities while speaking into a microphone.

She's hoping to compare the voices of patients with Alzheimer's to those with Parkinson's — both have similar symptoms in early stages of the disease — and find vocal differences which would also be different from those found in the voices of people who are aging normally.

If her research is successful, she hopes it will be an inexpensive way to spot Alzheimer's in early stages.

"What I would envision is to put this software on an app that can be used by the patient directly or in a medical facility," she told the Express.

"A patient or doctor could do a quick test with a vocal recording, and the score would indicate the likelihood of a neurological problem.

"If patients can be diagnosed in an early stage of disease, treatment and drug therapies can start at that time, possibly slowing the disease progression."

According to the National Institute on aging, more than 5 million Americans have Alzheimer's.
