'Ghajini 2' confirmed: How amnesia in Malayalam film 'Bougainvillea' differs from Suriya-Aamir Khan movie

The news that Suriya and Aamir Khan will shoot simultaneously for the sequel of the 2005 film Ghajini and will hit theatres on the same day has excited their fans. Interestingly, the makers are also planning a franchise for the film, as it still enjoys a cult following for its action sequences, unique storyline, and narrative style. With the news winning over social media discussions, many are also pondering how the new plot will engage the audience while doing justice to the medical condition of the central character - anterograde amnesia. Malayalam industry recently saw the release of the film Bougainvillea, in which the lead character suffered from a condition called retrograde amnesia. How are the two different? 

'Ghajini 2' and 'Bougainvillea' medical conditions
The Cleveland Clinic says that while retrograde amnesia (which Jyotirmayi's character suffers from in Bougainvillea) affects the ability to recall past memories, anterograde amnesia (Suriya - Aamir Khan characters' condition) hinders the capacity to form new memories. 
As for anterograde amnesia, it is often caused by a brain injury like in Ghajini, alcohol abuse or certain neurological conditions. It affects the present and future memories, and just like in the case of Suriya's character in Ghajini, those affected can struggle with daily tasks unless they put their own systems for them in place. Regardless, their emotional responses to the past may remain.

Cognitive therapy and memory aids are the most used methods to treat their condition. 
Head injuries or traumatic events often cause the condition of retrograde amnesia. The patients can still create new memories, but their responses to past events can be lost. Various occupational and reminiscence therapies are employed to help treat their conditions. Ghajini 2 has been trending on Google Trends for the past 24 hours with more than 10K search volume.
