Tumarkin跌倒發作

Tumarkin跌倒發作不會出現旋轉性的眩暈，特點是會在無預警、無意識喪失、無神經學或自律神經症狀的狀況下，突然向前傾倒或是向後傾倒，往往造成病患極大的恐慌。回顧相關的文獻可以發現，此病確切原因迄今仍未明，可能的病因為耳石斑受到不適當的刺激，引起線性加速（重力）感受的變化及前庭脊髓反射，於美尼攸氏病的發生率為5~72%不等。需與眩暈、昏厥、神經學症狀、猝倒及其他病變鑑別診斷，當設法排除中樞神經、心臟與血管的病變。Gentamicin注射之治療效果較保守藥物治療佳，前庭神經截斷術、球囊橢圓囊開洞術及迷路切除術可以治癒此病，但僅前庭神經截斷術可以保留聽力。比起其他原因所造成的跌倒發作，Tumarkin跌倒發作是相當良性的病。

Patients with drop attacks of Tumarkin (DAT) have sudden forward or backward falls that occur without whirling vertigo, without warning, without loss of consciousness, and without any concomitant neurological or autonomic symptoms or sequelae. The patients can be very frightened. To date, DAT are of unknown etiology in the literature reviewed. It is possible that a mechanical stimulus to the otolithic organ causes a perceptive change of linear acceleration (gravity) and a concomitant burst of vestibulo-spinal reflex. DAT are experienced by 5%~72% of patients with Meniere's disease. DAT should be differentiated from vertigo, syncope, neurological symptoms, cataplexy and other diseases. The possibility of central nervous, cardiac or vascular lesions should be ruled out. The therapeutic effect of gentamicin injection is better than conservative treatment. DAT can be cured by vestibular neurectomy, cochleosacculotomy or labyrinthectomy. However, hearing is only spared with vestibular neurectomy. Compared with other drop attacks, DAT is quite benign.
