Bipolar disorder and multiple sclerosis

Abstract: -Bipolar disorder may be overrepresented in multiple sclerosis (MS) patients. Although research in this area is limited, studies assessing the nature of this association have focused on genetic aspects, adverse reaction to drugs and brain demyelinating lesions. Herein we report three patients with MS that also presented bipolar disorder. The coexistence of neurological and psychiatric symptoms in most MS relapses highlights the relevance of biological factors in the emergence of mood disorders in these patient… Show more

“…Dosage is directly related to the incidence of adverse effects but is not related to the timing, severity, or duration of these effects [19]. Among MS patients treated with corticosteroids or ACTH, two systematic studies reported that 40% became depressed, 31% hypomanic, and 11% developed a mixed state and 16% a psychotic state [20]. Interestingly, these symptoms do not occur with every drug exposure and appear more frequently in case of a discontinuous treatment [21].…”

“…There are no published controlled treatment studies of bipolar disorder in MS. The cause of bipolar disorder in MS is unknown, but genetic factors, adverse reaction to drugs and brain-demyelinating lesions have all been invoked as possibilities [121]. Pseudobulbar affect, a condition of uncontrollable laughing or crying, also occurs in some patients and is sometimes referred to as pathological laughing or crying [122].…”

“…La première perspective considère l'explication endogène de la comorbidité : la SEP elle-même, de par ses lésions au système nerveux central, créerait aussi les manifestations psychiatriques (Figved et al, 2008;Goverover, Chiaravalloti, & DeLuca, 2005;Ybarra, Moreira, Araujo, Lana-Peixoto, & Teixeira, 2007). De façon générale, le lien établi entre les atteintes cérébrales et l'humeur concerne certaines régions spécifiques du cerveau, pas toujours les mêmes d'une étude à l'autre, comme la région temporale droite, l'atrophie frontale ou le volume de lésions global (Ghaffar & Feinstein, 2007;Sabatini et al, 1996;Schubert & Foliart, 1993;Wallin et al, 2006).…”
