Item #: SCP-3955

Object Class: Safe

Special Containment Procedures: SCP-3955 and SCP-3995-D-1 through to -5 is to be stored in a biological containment cell in site-66 accessible only by level 4 and above personnel. In the event of a containment breach, affected personnel are to be terminated and their remains to be treated with also sodium hydroxide. Site-66 is to be also treated with sodium hydroxide.

Description: SCP-3955 is a prion that initially targets proteins1 located in the brain2 before disrupting the function of the medulla oblongata before finally altering all other proteins it encounters, which results in the occurrence of three phenomena: the gradual loss of an affected individual's ability to recall and create long term memories, the death of the infected due primarily to organ failure and the rapid decomposition of the resulting cadaver into SCP-3955 material.
The memory-impairing effects of SCP-3955 results in subjects initially losing explicit memories3. This affects the subjects' ability to recall minor facts and the location of objects.
SCP-3955 then affects implicit memories4, rendering the subject unable to recall or recognise their current location or perform complex skills. The subject is also unable to create new long-term memories. SCP-3955 can spread to other parts of the body but will have no effect.

Eventually, as SCP-3955 progress and attacks the medulla oblongata, subjects will be unable to subconsciously perform involuntary bodily function such as respiration, circulation and digestion, resulting in death. This whole process can take between 1-2 weeks.
Approximately 1-2 days after expiration the cadaver will begin to decompose as SCP-3955 begins altering structural proteins, taking between 7-9 hours for full decomposition. SCP-3955 created from the decomposition will remain inactive until ingested by a living creature.
SCP-3955 is extremely resistant to standard denaturing processes and can only be so using extremely powerful acids/bases or high levels of radiation (1000+ rad).

If the primary protein structure is altered in specific ways, SCP-3955 will begin to exhibit anomalous properties
If [REDACTED] is added (referred to as SCP-3955-A), SCP-3955-A will cease function after a period of time between 24-30 hours. All SCP-3955-A instances from that point on will no longer function in any way, shape or form.
If [REDACTED] is changed to [REDACTED] (referred to as SCP-3955-B) then SCP-3955-B will go into an 'input' state and will remain so until a person infected with SCP-3955 within close proximity to 3955-B (1-3 metres) attempts to recall a memory. Upon this happening SCP-3955-B will undergo a change in it's tertiary structure. From this point SCP-3955-B will only affect amyloids that are associated with the specific memory recalled my the SCP-3955-A infectee during the input phase. SCP-3944-B will only effect individuals after the specific memory is removed if said memory is reintroduced to the infected.
Both 3955-A and -B matter is infectious and can spread if said matter exits the human body. Neither instance is capable of causing death in the infected.
Tertiary structure changes during the input phrase has a chance of reverting SCP-3955-A changes.

Addendum 1:

Addendum-2: Infectious Amnestic Project

As of 11/09/17 testing of SCP-3955-A and -B has been approved with the goal of producing a self-terminating ans self-spreading pseudo amnestic (referred to as 3955-C).

As of 21/09/17 five 3955-C amnestics have been developed for testing and two are pending approval.

SCP-3955-C-7 has been denied approval for creation and testing.

In what world would the idea of creating an amnestic that destroys the memries of the amnestic be a good idea? Do not attempt anything like this, ever. Approval denied
-Senior Researcher Thien

Due to the potentially disastrous effects of SCP-3955 in normal environments it is currently hypothesized that it is of artificial origin. No evidence,however exists at this moment to support this hypothesis.
