Familial hemiplegic migraine (FHM) is an autosomal dominant syndrome characterized by recurrent episodes of varying degrees of hemiparesis associated with migraine. The aura including hemiparesis may be prolonged and in severe attacks may often be associated with confusion or coma. Wedescribe a case ofFHMwhose aura was atypically prolonged and resulted in irreversible brain deficit which on magnetic resonance imaging (MRI) was suggestive ofcortical hyperperfusion. A subsequent MRI showed left brain atrophy.

Luminescence characteristics of Ce and Eu co-doped CaGa2S4 have been investigated for the first time. All co-doped samples showed the emission from Eu centers having a peak energy of ∼2.22 eV and they were found to have quantum efficiency values less than 30% for Eu doped sample under 441.6 nm excitation. Thermoluminesence was observed for all co-doped samples. These facts seem to indicate the existence of traps, which may mask the energy transfer from Ce to Eu in co-doped samples. Analyses of the measured transient thermoluminescence (TTL) showed two activation energies, ∼0.2 eV and ∼0.9 eV for most co-doped samples. A model where one trap level participates in two different activation processes is proposed to explain these two activation energies.
