Yes, lost memories can often come back, especially those "lost" due to trauma or retrieval issues, as the memory trace usually remains in the brain, but the neural pathways to access it get disrupted, and these pathways can sometimes be rebuilt or accessed through other routes, though permanent loss can occur with severe brain damage like in Alzheimer's or certain injuries. Techniques like looking at photos, listening to music, or therapy can help, but memories can also be unreliable and change over time.
At present, there's no way to treat memory loss itself. The main approach is to recognize and eliminate the underlying cause if possible, making it as easy as possible for your brain to heal.
According to Eysenck and Keane (2015), there are two avenues which repressed memories can be recalled: spontaneous recovery and recovered in therapy. Studies suggest that most recovered memories inside of a therapeutic session are often false memories.
They found that memories thought to be lost due to brain damage or disease might not be gone forever. Instead, they discovered that these memories could still exist in the brain and could potentially be brought back.
These memories are not simply forgotten but are actively blocked by the brain as a defense mechanism to protect people from emotional distress. However, they can resurface years or even decades later, often unexpectedly.
The 2-7-30 Rule for memory is a spaced repetition technique that boosts retention by reviewing new information at specific intervals: 2 days, 7 days, and 30 days after the initial learning, leveraging the brain's forgetting curve to solidify knowledge into long-term memory with minimal effort, making it great for studying languages, skills, or complex topics.
While all traumas leave a profound mark on an individual's life, there's a different level of difficulty in recovering from what's called "complex trauma." Unlike single-incident traumas, complex trauma stems from repeated experiences of stressful and traumatic events, usually in environments where there's no escape.
Long-term Memory: Painful events are often stored in long-term memory, especially when they carry intense emotions like fear or sadness. Information stored in long-term memory can be recalled even after a long time has passed.
12 Signs You're Repressing Childhood Trauma
These include:
It's completely normal to not remember much of your childhood, and this doesn't necessarily mean anything is wrong. Often, our limited recollections are based on normal memory development. But for some people, suppressed or fragmented memories may be the result of childhood trauma.
Therapists reported employing various techniques such as hypnosis, age regression, or instructions to remember, with these techniques being used in 42% of the recovered memory cases to aid recollection. In 21% of the cases, techniques were used before any memory had emerged.
The "3 C's of Trauma" usually refer to Connect, Co-Regulate, and Co-Reflect, a model for trauma-informed care focusing on building safe relationships, helping individuals manage overwhelming emotions (co-regulation), and processing experiences (co-reflection). Other "3 C's" include Comfort, Conversation, and Commitment for children's coping, and Catch, Check, Change from Cognitive Behavioral Therapy (CBT) for challenging negative thoughts in trauma recovery.
Over time, these memories may then be stored in other parts of the brain, namely the neocortex. One of the potential mechanisms through which memories are stored in the hippocampus and neocortex, is via the co-activity of neurons across different areas.
Five key signs your brain might be in trouble include significant memory loss (forgetting important things or familiar routines), difficulty with everyday tasks, confusion about time/place, problems with language/communication, and noticeable personality or mood changes, such as increased irritability or loss of interest in hobbies, which signal potential cognitive decline or neurological issues.
Memory loss is unusual forgetfulness. You may not be able to remember new events, recall one or more memories of the past, or both. The memory loss may be for a short time and then resolve (transient). Or, it may not go away, and, depending on the cause, it can get worse over time.
Jonice Webb, (reference at end) describes a range of symptoms of childhood emotional neglect in adulthood:
In univariate analyses, all 5 forms of childhood trauma in this study (ie, witnessing violence, physical neglect, emotional abuse, physical abuse, sexual abuse) demonstrated statistically significant relationships with the number of different aggressive behaviors reported in adulthood.
The "8 childhood traumas" often refer to common Adverse Childhood Experiences (ACEs) from the CDC, including physical abuse, emotional abuse, sexual abuse, physical neglect, emotional neglect, household substance abuse, a household member with mental illness, and parental separation/divorce, though these can be expanded to include things like violence, discrimination, or sudden loss, which profoundly impact a child's development and well-being. These experiences, especially repeated ones (complex trauma), disrupt a child's sense of safety, leading to issues with trust, emotional regulation, and relationships, often manifesting as anxiety, depression, or attachment problems in adulthood.
The time when the brain works most rapidly is around age 18 or 19; short-term memory peaks at around age 25; and the ability to read other people's emotional states is optimal in one's 40s and 50s. When one is a senior, in their 60s or 70s, “crystallized” intelligence is the strongest.
A recent study found that when people try to remember something they've forgotten, their brains still activate regions associated with memory. This neural activity subtly influences choices—even if the memory never fully resurfaces.
Highly Superior Autobiographical Memory (HSAM) is a rare form of exceptional memory characterised by an enhanced ability to remember autobiographical content (LePort et al., 2012; Patihis et al., 2013).
Symptoms may include flashbacks, nightmares, severe anxiety and uncontrollable thoughts about the event. Most people who go through traumatic events may have a hard time adjusting and coping for a short time. But with time and by taking good care of themselves, they usually get better.
“For trauma survivors, especially those who've experienced neglect or emotional invalidation, oversharing can feel like a fast-track to safety or intimacy — even if it bypasses healthy relationship pacing.” Figueroa adds that you might also overshare intimate details to avoid feeling rejected or unseen.
It won't rid you of PTSD and your fears, but let your tears flow and you'll maybe feel a little better afterwards. 'Crying for long periods of time releases oxytocin and endogenous opioids, otherwise known as endorphins. These feel-good chemicals can help ease both physical and emotional pain.
