Introduction
Numbness is one of the most common neurological symptoms experienced by both patients and Neurologists. Numbness refers to a loss of feeling in a part of the body. One-sided numbness is very important symptom because it may be the early symptom of Stroke, a life-threatening condition. Thus, I advise all patients who have one-sided numbness to immediately seek Neurologist attention.
What are the causes of numbness?
Stroke
The sudden onset of one-sided numbness should alert the possibility of Stroke, especially when there are other symptoms such as difficulty in speaking, spinning sensation (vertigo), weakness of legs and blurring of vision. The presence of risk factors for Stroke such as high blood pressure, high cholesterol level and Diabetes increases the possibility of Stroke as the cause of numbness.
Spinal Cord Disorders
Spinal cord disorder such as Disc Prolapse or tumours can cause numbness.
Peripheral Neuropathy
This refers to abnormal function of the nerves at hands and feet, which is most commonly caused by Diabetes, especially when Diabetes is severe or poorly-controlled. Patients have numbness of both hands and feet. Occasionally, vitamin B12 deficiency can cause similar symptoms.
Emotional Disorders
It has to be emphasized again emotional disorders such as Anxiety disorder and Depression can cause numbness. People who have Anxiety disorder often present with numbness of lips, hands and feet, especially during panic attacks (characterized by difficulty in breathing and palpitation).
When should a patient with numbness consult the Neurologist?
As numbness can be caused by Stroke or severe Diabetes (which can be life-threatening), I suggest that all patients with numbness consult the Neurologist.
What will the Neurologist do for patients with numbness?
The Neurologist will perform physical examination, blood tests, CT / MRI brain scan and Nerve Conduction study / EMG.
