Post-dural puncture headache (PDPH) is a frequent complication of lumbar puncture, performed for diagnostic or therapeutic purposes or accidentally, as a complication of epidural anesthesia. As PDPH can be disabling, clinicians who perform these procedures should be familiar with strategies for preventing this disorder. Since the best preventative measures sometimes fail, clinicians should also be familiar with the therapeutic approaches for PDPH. Herein, we review the procedure-related risk factors for PDPH, the prognosis of PDPH and the studies of PDPH treatment. We divide the therapeutic approach to PDPH into 4 stages: conservative management, aggressive medical management, conventional invasive treatments, and the very rarely employed less conventional invasive treatments and provide management algorithm to facilitate treatment.

Headache is one of the most common neurological symptoms reported by patients with thrombotic thrombocytopenic purpura (TTP). Reports of headache characteristics in patients with TTP are rare. We report 2 cases of headache in a setting of TTP and review previous reports. Headache in TTP can have features in common with both migraine and tension-type headache. Although the pathophysiology of headache in TTP is not certain, platelet aggregation and activation may play a key role.

Headache associated with moyamoya disease (HAMD) is common in moyamoya disease. However, the characteristics and classification of HAMD are largely unknown. We present a case of a 39-year-old woman with HAMD. To characterize and classify the features of this syndrome, the patient was asked to complete a 4-month diagnostic headache diary. There was a total of 15 ictal days. All episodes were without aura. The headache was more commonly pressing (10/15), mild to moderate in severity (14/15), unchanged by physical activity (11/15), and associated with photophobia (10/15). The International Headache Society Classification was utilized to determine that eight episodes met criteria for probable migraine without aura, while seven episodes met criteria for probable frequent episodic tension-type headache. We identified four other case reports of HAMD with partial descriptions of the characteristics. When combined with our patient, the median age was 34 years old (range 6–49, SD 16). Four were female, while the patient with cluster headache was male. The median time from headache onset to diagnosis with moyamoya disease was 9.5 months (range 0–192, SD 88.0). Headaches were described as migraine with aura in two of five cases, hemiplegic migraine in one of five, and cluster headache in one of five. The highest intensity was described as severe in three of three cases, in which headache intensity was reported. Meanwhile, nausea, vomiting, and photophobia were present in two of three cases, where these features were reported, while nausea without vomiting was seen in one of three cases. In all five cases, patients had other neurological symptoms, such as paresis, seizures, visual disturbances, dysarthria, allodynia, ptosis, and unilateral restless leg syndrome. In conclusion, HAMD can present as migraine without aura. It can be the first presenting symptom of moyamoya disease. The headache features are not diagnostic; hence, early neurovascular imaging should be considered in patients with new onset, refractory migraine-like headache, especially in the setting of other neurological symptoms to exclude underlying moyamoya disease. Further reports using headache diaries are needed to better characterize HAMD as well as to determine whether headache with tension-type features is also part of this condition.

Post-dural puncture headache (PDPH) is a frequent complication of dural puncture whether performed for diagnostic purposes or accidentally, as a complication of anesthesia. Because both procedures are common, clinicians interested in headache should be familiar with this entity. The differential diagnosis of PDPH is broad and includes other complications of dural puncture as well as headaches attributable to the condition which lead to the procedure. The patterns of development of PDPH depend on a number of procedure- and nonprocedure-related risk factors. Knowledge of procedure-related factors supports interventions designed to reduce the incidence of PDPH. Finally, despite best preventive efforts, PDPH may still occur and be associated with significant morbidity. Therefore, it is important to know the management and prognosis of this disorder. In this review, we will highlight diagnosis and clinical characteristics of PDPH, differential diagnosis, frequency, and risk factors as well as pathophysiology of PDPH.
