As swallowing is a complex process, there are many reasons why dysphagia can develop.
Some causes of dysphagia are explained below.
The word neurological refers to the nervous system. This is made up of the brain, nerves and spinal cord.
Damage to the nervous system can interfere with the nerves responsible for starting and controlling swallowing. This can lead to dysphagia.
Some neurological causes of dysphagia include:
neurological conditions that cause damage to the brain and nervous system over time, including Parkinson's disease, multiple sclerosis, dementia and motor neurone disease
myasthenia gravis - a rare condition that causes your muscles to become weak.
