How many confusion !! URGH !! - sweety_usmle - ArchivalUser - 09-26-2014 So, this one is between Spinal Muscle Atrophy and Cerebral Palsy.. How to differentiate which one is which simply from history and presenting features?? 0 - ArchivalUser - 09-26-2014 http://slink.co/4a515 0 - ArchivalUser - 09-27-2014 Guys any thought !! 0 - ArchivalUser - 09-27-2014 Spinal Muscular Atrophy This disruption of neural impulse transmission due to destruction of motoneurons causes the following symptoms in the locomotor system: Muscular atrophy Pareses (paralyses) Hypotension of the muscles (reduction of muscle tension) Swallowing, chewing and speech dysfunctions with involvement of the motoneurons of the brain stem (Mostly FLACCID ) http://harms-spinesurgery.com/src/plugin.php?m=harms.SKO10.03E From Kaplan: (pg 212) - Progressive hypotonia; generalized weakness; Infant is flaccid, has little movement and poor head control − Feeding difficulty − Respiratory insufficiency − Fasciculations of the tongue and fingers − Absent DTRs *--------*-------*-------* Kaplan (pg 210) Now, Cerebral Palsy • The most obvious manifestation is impaired ability of voluntary muscles (rigidity and spasticity). − Other associationsseizures and abnormalities of speech, vision, and intellect *------*------*-------* So, Cerebral Palsy: Think of "Rigidity" Spinal Muscular Atrophy: Think of "Flaccidity" 0 - ArchivalUser - 09-27-2014 As also Spinal Muscular Atrophy : LMN Symptoms (destruction of motorneurons) Cerebral Palsy: UMN Symptoms (Structural problems in the brain are seen in 80% of cases, most commonly within the white matter) 0 - ArchivalUser - 09-27-2014 Thank you so much!!
