Noting that Greeks are an ethnic group indigenous to Greece and the Levant, artefacts can be found from this region. Ancient authors frequently mention the ὀφθαλμὸς βάσκανος (evil eye). Classical authors attempted both to describe and to explain the function of the evil eye. Plutarch in his work entitle Symposium has a separate chapter describing such beliefs. In his scientific explanation stated that the eyes were the chief, if not sole, source of the deadly rays that were supposed to spring up like poisoned darts from the inner recesses of a person possessing the evil eye. Plutarch treated the phenomenon of the evil eye as something seemingly inexplicable that is a source of wonder and cause of incredulity. Pliny the Elder described the ability of certain African enchanters to have the "power of fascination with the eyes and can even kill those on whom they fix their gaze".The idea of the evil eye appears in the poetry of Virgil in a conversation between the shepherds Menalcas and Damoetas. In the passage, Menalcas is lamenting the poor health of his stock: "What eye is it that has fascinated my tender lambs?". Ancient Greeks and Romans believed that the evil eye could affect both humans and animals, for example cattles. Protection from the eye
The belief in the evil eye during antiquity varied across different regions and periods. The evil eye was not feared with equal intensity in every corner of the Roman Empire.
Logopenic progressive aphasia (LPA) is a variant of primary progressive aphasia. It is defined clinically by impairments in naming and sentence repetition. It is similar to conduction aphasia and is associated with atrophy to the left posterior temporal cortex and inferior parietal lobule. It is suspected that an atypical form of Alzheimers disease is the most common cause of logopenic progressive aphasia.Although patients with the logopenic variant of PPA are still able to produce speech, their speech rate may be significantly slowed due to word retrieval difficulty. Over time, they may experience the inability to retain lengthy information, causing problems with understanding complex verbal information. Some additional behavioral features include irritability, anxiety and agitation.Compared to other subtypes of primary progressive aphasia, the logopenic variant has been found to be associated with cognitive and behavioral characteristics. Studies have shown that patients with the logopenic variant perform significantly worse on tests of calculation than other primary progressive aphasia patients. Several logopenic variant patients, especially those with Alzheimers disease pathology, have also been found to perform poorly on memory tasks.Logopenic progressive aphasia is caused by damage to segregated brain regions, specifically the inferior parietal lobe and superior temporal regions. Difficulties in naming are produced from the thinning of the inferior parietal lobe. Damage to the dorsal pathways creates language deficiency in patients that is characteristic of logopenic progressive aphasia. See also
