  2. Exceptional episodic memory
  3. Ability to recall minor events
  4. Exceptional capacity of memorizing



Hyperthymesia Causes


At the moment, we do not have enough clinical data to find out exact mechanism that triggers hyperthymesia. However, various studies and laboratory findings reveals that person having hyperthymesia have enlarged temporal lobe and caudate nucleus. Temporal lobe is important part of brain because it contains various components that are regulating process of semantic memory and episodic memory.



Hyperthymesia Treatment


Hyperthymesia is neither pathological condition nor it is intense clinical emergency condition that requires prompt intervention. Though, It is some kind of functional deviation from normal process but becoming a person that have super memory is not undesirable. Clinically, person having hyperthymesia have no complaints regarding his or her mental activity so, no intervention is required unless patient feels some kind of functional or structural disturbance in cerebral region.


Hyperthymesia Test


Hyperthymesia tests can be categorized into 3 parts.

Motor function Tests


Motor function test are performed to check neuronal activity of brain during movement, speech and
memorizing.These tests include

  1. Visual motor functions test
  2. Lateralisation
  3. Executive function test
  4. Pattern recognition test
  5. Language ability test

Radiographic scanning


Radiographic scanning is performed to examine internal structures cerebral region to rule out any structural abnormality if person complaints other than usual. These tests include

  1. Magnetic resonance imaging (MRI) test
  2. Computerized tomography (CT-Scan) test

Electrophysiological tests


Electrophysiological tests are conducted to examine rhythmic activity of cerebral area.These tests include

  1. Electroencephalograph (EEG)

In hyperthymesia person have deep autobiographical memory of events that happened previously while Eidetic memory is characterized by a state in which person have vast and strong photographic memory. Person with eidetic memory has ability to recall anything seen in past like face recognition, scene recognition etc.
 


How to get Hyperthymesia


Though it is unusual pattern but it imparts exceptional memorizing capacity that is desirable to everyone. It is God gifted trait that can not be achieved through medical assistance or by doing something.



Highly superior autobiographical memory (HSAM)


Highly Superior Autobiographical Memory (HSAM) is a rare kind of state that was discovered few years ago. It is a condition in which  the person can recall the vast majority of personal experiences and events in their lives. Generally this state is know as hyperthymesia but clinical point of view it is defined as Highly superior autobiographical memory (HSAM).


Hyperthymestic Syndrome


Clinically, hyperthymesia is often pronounced as hyperthymestic Syndrome to make it more understandable for medical professionals. Hyperthymestic Syndrome can be defined as highly superior autobiographical Memory (HSAM) that enables the individual to memorize vast number of events that happened previously.
