What is the Difference Between Mental Illness and Neurological Disorder

Thekey differencebetween mental illness and neurological disorderis that mental illness stems from changes in an individual’s emotions, thoughts, behaviors, and their interactions with the external world, whereas neurological disorders stem from dysfunction within the nervous system.

Mental illnesses and neurological disorders have a deep connection to each other. This is because neurological disorders involve damage to the nervous system, and this damage can sometimes alter the communication between the neurons. When this happens, it can manifest problems in behavior, body control, memory, and mood, ultimately leading to mental illness.

Some well-known examples of neurological disorders aremyelopathy,epilepsy, myelitis, and Alzheimer’s disease. Moreover, common symptoms of the neurological disorder are persistent headache, a headache that changes, loss of feeling, weakness of muscle, memory loss, impaired ability, lack of coordination, muscle rigidity, tremors or seizures, back pain, muscle wasting, slurred speech, and new language impairment. The risk factors for this condition are early exposure to chlamydia pneumonia, Epstein-Barr virus, human herpes virus-6, measles, canine distemper, and other viruses or bacteria in the life, living in an area of less sun exposure, and personal history of smoking.

Neurological disorders can be diagnosed through physical examination, neurological examination, and imaging tests such as CT scan, electroencephalogram, MRI, PET scan, arteriogram, and cerebral spinal fluid analysis. Furthermore, treatment options for neurological disorders may include lifestyle changes, physiotherapy, pain management, medications to either restore function or prevent a worsening of the condition, cognitive therapy, and behavioral therapy.
