Idiopathic Generalized Epilepsy and Hypokalemic Periodic Paralysis in a Family of South Indian Descent

Table 1

The onset and clinical presentation of both hypokalemic periodic paralysis and idiopathic generalized epilepsy in the family.

Patient	Age/sex	Age at onset		Serum K+	Frequency of paralysis	EMG	EEG
		HHP	IGE	(During attack)		(During attack)
I 2	62 F	32	31		1-2 times per year
II 1	32 M	23	16	2.1 mEq/L	Once a week	CMAP of low amplitude	Bilateral slow wave discharge
II 3	28 M	20	18	2.2 mEq/L	1-2 times a month	Complete electrical silence	Bilateral spike-wave discharge
III 1	11 M	4		1.9 mEq/L	4-5 times a month	CMAP of low amplitude
III 5	26 M	21	19	1.9 mEq/L	Rare attacks	Complete electrical silence	Bilateral spike- wave discharge

HHP, hypokalemic periodic paralysis; IGE, idiopathic generalized epilepsy; EMG,electromyography; EEG, electroencephalography.
