This headache is usually made worse by standing and typically becomes prominent throughout the day, with the pain becoming less severe when lying down. Orthostatic headaches can become chronic and disabling to the point of incapacitation. Some patients with a SCSFL will develop headaches that begin in the afternoon. This is known as second-half-of-the-day headache. This may be an initial presentation of a spontaneous CSF<unk>  or appear after treatment such as an epidural patch, and likely indicates a slow CSF<unk> . While high CSF pressure can make lying down unbearable, low CSF pressure due to a<unk>  can be relieved by lying flat on the back. About 50% of people with a CSFL experience neck pain or stiffness, nausea, and vomiting. Other symptoms of a CSF<unk>  include photophobia, dizziness and vertigo, gait disturbances, tinnitus, facial numbness or weakness, visual disturbances, brain fog or difficulties with concentration, neuralgia, fatigue,<unk>  dripping from the nose or ears, Aural symptoms are also present in many cases of intracranial hypotension due to CSF<unk> ; including muffled hearing, pulsatile tinnitus, hearing loss. Less common symptoms include double vision (due to cranial nerve 6 palsy) or tremor. Movement disorders are uncommon in spontaneous CSF<unk> s but occasionally can be one of the major components of the clinical presentation. Some cases of chronic intracranial hypotension due to CSF<unk>  may present as personality changes, altered behaviors and impairment of executive functions, similar to behavioral-variant frontotemporal dementia as the frontal and temporal lobes are affected by downward sagging due to reduced intra-cranial pressures. An untreated CSF<unk>  can result in coma or death as late stage findings as the brainstem herniates through the skull base or foramen magnum .
