Re: Constant foot and leg shaking

[Anonymous]

Restless Legs Syndrome (RLS) is a condition in which subjects feel an urge to move the legs due to feelings of pain and discomfort that have been described as “tickles”, “bugs”, “spiders”, and “a lot of energy in the legs” by patients (Picchietti et al., 2008). The urge to move becomes stronger after long periods of inactivity, particularly toward the end of the day, and is relieved by movement (The International Restless Legs Syndrome Study Group). RLS is, consequently, associated with considerable motor restlessness. Moreover, up to 80% of RLS cases are accompanied by Periodic Limb Movement in Sleep (PLMS), which is characterized by the presence of periodic and repetitive limb movements that last 0.5-5.0 seconds and occur more than 5 times an hour during sleep.

Association of RLS/PLMS with ADHD

A number of studies have provided evidence to suggest that there is an association between RLS/PLMS and ADHD. While two studies reported no differences in the prevalence of PLMD in ADHD compared to controls (Wiggs et al., 2005; Chervin et al., 1997; Sangal et al., 2005), seven studies reported a higher prevalence of either RLS, PLMS, or limb movement during sleep in ADHD (Picchietti et al., 1998; 1999; Golan et al., 2004; Konofal et al., 2001; Oner et al., 2007; Konofal et al., 2003; Wagner et al., 2004).

I hope that helps. Unfortuantely treatment has varied from low iron treatment to increased exercise. I think, anecdotally, that it is a withdrawal effect of the medications in the evening but yet to prove this.
