Impact on Memory

Impacts on memory

In normal circumstances memories are processed and are strengthened over a period time. Re-consolidation is the process whereby memories are recalled and made stronger or modified. In PTSD fearful memories may be more vivid due to the presence of stress hormones such as epinephrine that play a critical role in consolidating memories. They can be much more easily triggered by sensory stimuli as they haven’t been fully processed. It is in our interest to be attentive to fearful memories in order to protect ourselves in the future. Trauma focused therapies can help with re-processing those memories
in order to let you know you are no longer at risk.

Problems with memory are mostly due to difficulties with attention and taking on board information. This then impacts on everyday recall. Difficulties with attention can be due to problems managing intrusive memories or thoughts, or from hyper-vigilance. Hyper-vigilance is an enhanced state of sensory sensitivity accompanied by an exaggerated intensity of behaviours which is in order to detect other threats. Hyper-vigilance may bring about a state of increased anxiety which can cause exhaustion. Imposing external structure (routines, planners or diaries, prompts, checklists, etc.) reduces the mental load and can improve attention and therefore memory.
