| Introduction|| |
Hirayama disease, also known as monomelic amyotrophy or benign focal amyotrophy, is a rare motor neuron disease which was first described in 1959 in Japan by Hirayama et al., It is reported to primarily affect males of Southeast Asia, particularly India and Japan. The symptoms usually appear during the second or third decade of life. The characteristic features as originally described by Hirayama include:
- Weakness and wasting predominantly in C7, C8, and T1 myotomes of unilateral upper limb or asymmetrically in bilateral upper limbs with sparing of brachioradialis
- Insidious onset in teens or early twenties
- Progression of 1 to 3 years followed by arrest of disease or relatively benign course
- Irregular-course tremors (minipolymyoclonus) in the fingers of the affected hand(s)
- Mild transient worsening of symptoms on exposure to cold
- Electromyography evidence of chronic denervation in the clinically or subclinically affected muscles
- The absence of substantial sensory loss/reflex abnormalities, cranial nerve, pyramidal tract in the lower limb, sphincter, or cerebellar deficits.
The disability originates with impaired functioning of the anterior horn cells of the lower cervical cord. Researches reveal that the contributing factors are the forward displacement of the cervical dural sac and compressive flattening of the lower cervical cord during neck flexion. Magnetic resonance imaging (MRI) cervical spine in flexion would reveal the cardinal features of Hirayama disease.
| Case Report|| |
Here, we report a case of Hirayama disease that approached and underwent Ayurveda management.
A 27-year-old software engineer, with a history of keyboard typing and bike rides for long hours, had a relevant clinical history of frequent episodes of migraine and sinusitis, occasionally followed by pain at the cervical region since the age of 12 years, and approached the Ayurveda Outpatient Department, at KLE Ayurveda Hospital and Medical Research Centre, Belagavi, Karnataka.
Previously diagnosed as a case of Hirayama disease, the patient presented with a history of gradual onset of weakness and tremors in his right hand since the age of 18 years. The condition progressed over the past 9 years to generate the same symptoms in the left hand and in addition, he developed wasting at the right tríceps muscle. Three months ago, while performing aerobics, he suddenly developed drooping of the right ring finger along with loss of sensation in the same finger. The symptoms were observed to aggravate on exposure to cold environment. In addition, occasional pain at the cervical region radiating to the left upper limb was reported. During his course of evaluation and treatment at contemporary health care, he underwent a series of investigations wherein his Vitamin B12 level was 123 pg/mL and Vitamin D level was 15.21 ng/mL, which were found to be low. Electromyogram study conducted in July 2016 showed low amplitude of bilateral median and ulnar nerves. MRI of the flexed cervical spine performed in July 2016 revealed that on sagittal sequences, the normal cervical lordosis seemed to be altered. Incidentally, Schmorl's impressions were noted along contiguous disc surface of the C7–T1 level. The posterior subarachnoid space at C2–C3 levels appeared reduced in comparison to the anterior space, in neural and flexion positions. In addition, on flexion images, the C5–C6 intervertebral disc and posterosuperior aspects of C6 vertebra were seen contacting the anterior cord silhouette, thus confirming focal cord T2 hyperintense signals at C5–C6 level and C4–C5 and C5–C6 posterior disc protrusions, causing minimal thecal compressions.
- Thus, he was diagnosed as a case of Hirayama disease, and was advised to undergo surgery. The patient then approached Ayurveda consultation for conservative line of management.
On physical examination, he was conscious and well oriented to person, place, and time. In comparison to the left hand, more tremors were present in the right hand with reduced palmar grasp. There was reduced sensation at the right ring finger along with minipolymyoclonus. Wasting along with mild fasciculation was observed at the right tríceps muscle. Deep tendon reflexes were found to be diminished in the right upper limb.
Based on his clinical and radiological findings, he was diagnosed as a case of Viswachi (neuralgic amyotrophy) and was put on Ayurveda line of treatment.
Classical ayurvedic therapeutic procedures were administered through nasal and rectal routes internally, and few external procedures were carried out in order to strengthen the spinal cord (nervous system). During the first course, Nasya Karma (Errhine therapy), that is, nasal instillation of medicated oil, was administered for a period of 7 days. For the initial 3 days, Shodhana nasya (to achieve purificatory effect) was administered using Shadbindu taila and for the next 4 days, Brinhana nasya was administered using Ksheerabala taila (101), whereas during the second course, Basti Karma (enema therapy), that is, medications through rectal route, was the focus of the treatment. External procedures such as Sarvanga abhyanga (whole-body oil massage), Prishtha basti (retaining medicated oil on back), Patra pinda sweda (hot sudation with herbal leaves), and Dashanga lepa (application of medicated paste) were performed for supportive symptomatic relief. The details of the treatment are summarized in [Table 1], [Table 2], [Table 3], [Table 4].

The patient is under monitoring through annual visits and regular phone call conversations. After 3 years of follow-up, the patient reported 30% relief with no aggravation of symptoms. He was asked to take the opinion of a neuro-physician who stated that there was no further progression of the disease.
| Discussion|| |
Hirayama disease is a self-limiting condition diagnosed through flexion MRI. The condition is observed to exhibit with wide presentation in different individuals. In Ayurveda, the present condition can be dealt under the spectrum of Vata vyadhi (disorders of nervous system) and was diagnosed as a case of Viswachi (neuralgic amyotrophy), wherein the pain evolves from the nape of the neck (manya) and radiates to either of the bilateral upper limbs. Assessing the chronicity of the condition, multiple courses of treatment were planned with the expectation of obtaining maximum relief.
During the first course, Nasya Karma (Errhine therapy), that is, nasal instillation of medicated oil, was administered as the prime management, as indicated in Viswachi to achieve target action. It has been well established that the mucus membrane of the nose is highly vascular and absorption through it is directly into the cerebrospinal fluid via inferior ophthalmic veins. The networks of nasal blood and lymph vessels stimulate the nerve endings of the olfactory and trigeminal nerves and impulses are transmitted to the central nervous system (CNS). Researchers show that the blood–brain barrier is highly permeable for lipid substances and thus, the medicated oil passes this barrier to exert its action on CNS and strengthens the nervous pathway.
As Viswachi is one among the Vatavyadhi, the second course of treatment was planned to pacify Vata Dosha, that is, Basti Karma (administration of medicated enema through rectal route). Recent advancements suggest the Gut Brain theory, wherein the stimulation of gastrointestinal tract activates certain aspects of the CNS and thus exhibits its action. In addition, its ability to by-pass the first-pass effect and absorb directly into the systemic circulation results in pacifying the Vata Dosha and strengthens majja dhatu (bone marrow), thereby reducing the symptoms such as tingling, pain, and weakness.
External procedures such as Sarvanga abhyanga (whole-body oil massage), Prishtha basti (retaining medicated oil on back), Patra pinda sweda (hot sudation with herbal leaves), and Dashanga lepa (application of medicated paste) contain drugs that are fat and water soluble. These medications when rubbed over the skin surface enhance the micro-circulation (blood plasma), thereby strengthening the local tissues and aiding in relieving symptoms.
The herbo-mineral preparations when administered orally help in nerve stimulation, prevent neuronal degeneration, re-establish micro-circulation, relieve muscle stiffness, and improve neuro-muscular fine co-ordination. Ashwagandha (Withania somnifera) in particular is proven to contain phytosteroidal properties that aid in preventing the myelin sheath discontinuation. Further, Rajata bhasma and Abhraka bhasma (nano particles of calcined argentum and mica) are excellent brain nutrients in preventing spinal and cerebral atrophy.
| Conclusion|| |
The case presented above was observed to progress for a period of 9 years. Although the radiological findings showed slight variation in the presentation of typical features, the clinical features suggested it as more of Hirayama disease. The patient showed good clinical improvement with stabilization of the condition on receiving Ayurveda line of management. Hirayama disease is a less common disorder and thus, patients approaching Ayurveda center are still rare. In this case, we have made an effort to frame a treatment protocol to manage the condition through Ayurveda.
