loss of Housetraining skills. [ 8 ] Affected cats may wander aimlessly and look lost in space, seem restless and anxious, fail to recognize familiar faces such as their owners, caretakers or other cats in the clowder, display decreased interest in social interactions or increased aggression, experience insomnia, sometimes along with increased ...
Hippocampal sclerosis (HS) or mesial temporal sclerosis (MTS) is a neuropathological condition with severe neuronal cell loss and gliosis in the hippocampus. [1] Neuroimaging tests such as magnetic resonance imaging (MRI) and positron emission tomography (PET) may identify individuals with hippocampal sclerosis. [ 2 ]
[16] One study found "subtle hippocampal volume loss" in patients with TEA, but the atrophy did not correspond to measures of either ALF or autobiographical memory loss, suggesting "a more diffuse physiological basis rather than being a consequence of structural damage." [14] Anticonvulsant medication; Antiepileptic drugs sometimes affect memory.
Hippocampal sclerosis occurs with severe CA1 and less severe CA3 and CA4 neuronal loss. [27] Experimental research has shown that N-methyl-d-aspartate (NMDA) receptor activation causes neuronal cell loss, and electrical stimulation-induced animal models of temporal lobe epilepsy duplicate the cell loss pattern of temporal lobe epilepsy in ...
Cerebral atrophy is a common feature of many of the diseases that affect the brain. [1] Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins.
Affected cats may also display poor judgement of distance, and some cats may develop a rapid, crouching, hypermetric gait. Some affected cats may exhibit an abnormal head tilt, tremors, a vacant stare, excessive salivation, decreased grooming behaviors, polyphagia , and dilated pupils. [ 3 ]

Reduced hippocampal neurogenesis leads to a reduction in hippocampal volume. A genetically smaller hippocampus has been linked to a reduced ability to process psychological trauma and external stress, and subsequent predisposition to psychological illness. [126] Depression without familial risk or childhood trauma has been linked to a normal ...
