The manifestations of occult spina bifida include the following: 1. In childhood, especially between the ages of 3 and 6, it can manifest as bedwetting, which means that the child’s urination is uncontrollable. 2. If it is more severe, it may cause, for example, fecal incontinence, urinary incontinence, or even sensory and motor disorders of both lower extremities, or perineal sensory disorders may occur. 3. If spina bifida is combined with spinal cord embolism, there may be more serious manifestations, especially sexual dysfunction, urinary and fecal disorders, and even some impairment of muscle strength, sensation, and movement of both lower extremities. 4. If spina bifida is not too serious, with the development of the disease, it may also appear to heal itself, and there are no serious clinical symptoms, and there is no big difference with normal people.
