Inability to get out of bed along with no energy is called cataplexy and its treatment is available. (sodium oxybate,antidepressants,SSRI). third problem you have mentioned can be a part of same spectrum of disease, but a workup is mandatory for root cause as its highly debilitating to lose vision .get your carotid doppler study, echocardiography with bubble study and an MRI brain,if advised by your neurologist. Hope I have answered your query. Let me know if I can assist you further. Take Care Regards. Dr. FAISAL BACHA, MEDICAL SPECIALIST (FCPS INTERNAL MEDICINE)
