Do you know what is Dysarthria?
Dysarthria is a condition in which a person has difculty in

nerves. It affects a person's ability to control their tongue and
voice box, causing slurred and unclear speech.

It can occur at any age from childhood to old age.

Causes of Dysarthria

Dysarthria is caused when there is damage to some areas of
the brain which results in an interruption in the blood ow.
Following are the major causes of dysarthria:
Ÿ Stroke: In conditions of stroke, blood ow is
interrupted preventing oxygen and nutrition supply to
brain cells and can cause dysarthria in 8 to 60% of
individuals

Ÿ Road accidents can cause injury to the speech-
related areas of the brain leading to dysarthria.

Ÿ Tumour in the brain affects areas that control
speaking. It is one of the major causes of dysarthria
Ÿ Infections such as brain fever (meningitis,
encephalitis) can cause cell damage in major centers
of the brain that controls speech.
