Clive Kempson suffered a stroke at work in 2015 and developed depression a few weeks later.

Self-employed, Mr Kempson worried he wouldn't be able support his family and at his worst, he considered suicide.

"I was also internally questioning myself about how other people look at me," Mr Kempson told AAP on Tuesday.

New research suggests reducing the use of medications to treat post-stroke depression.

Researcher Maree Hackett from the George Institute said antidepressants carried side effects, like confusion or gastrointestinal problems, which could put stroke victims off taking them.

Professor Hackett said untreated depression in stroke victims could stop them from undergoing physical rehabilitation.

"If they have lost all motivation then they're less likely to make the important lifestyle changes they need to make to avoid a second stroke," she told AAP.

Instead of medication, Professor Hackett recommends more use of therapies to treat depression.

She said depression among stroke victims was common, often attributed to people experiencing a life-threatening event, coupled with the stroke's physical effects on the brain.

Stroke victims may be no longer able to drive, hold down a job or simply walk the way they did beforehand.

Since his stroke, Mr Kempson has been through six psychologists before finding one that was the right fit.

But he says more is needed for any Australian with a proven mental health condition.

Mr Kempson wants the government to increase from 10 the number of subsidised sessions with psychologists, therapists or counsellors each year for people with mental health plans.

"People who haven't suffered from depression and anxiety really don't get it," he said.

"There should be some way of the government funding all those extra sessions when its been proven that you need it."
