**“It Explained So Much”: Majella O’Donnell’s Late ADHD Diagnosis Casts a New Light on a Lifetime of Restlessness**
**Majella O’Donnell details the signs and symptoms that led to her adult ADHD diagnosis**
For many years, **Majella O’Donnell** lived with certain habits and reactions that seemed to be part of her natural personality. She was energetic, enthusiastic and frequently filled with new ideas. She could become completely absorbed in a project, yet at other times struggle to maintain concentration, remain organised or quietly wait for her turn in a conversation. Only later in life did she receive an explanation that brought many of those experiences into sharper focus: a diagnosis of **attention-deficit/hyperactivity disorder, commonly known as ADHD**.
Majella has revealed that she was formally diagnosed approximately two years ago after members of her own family received similar diagnoses. Her sister’s two children were diagnosed first, followed by her sister. That family connection prompted Majella to wonder whether the condition might also help explain patterns she had experienced throughout her life. She subsequently underwent an extensive private assessment lasting around three hours and was diagnosed with ADHD. According to Majella, the result helped numerous pieces of her personal history finally make sense.
Her decision to speak publicly is particularly meaningful because **ADHD in adult women can remain unnoticed for decades**. The NHS explains that women are less frequently recognised as having ADHD, partly because they may display inattentive symptoms that are less visible than the more obvious hyperactivity traditionally associated with the condition. Adult signs may include distractibility, forgetfulness, difficulty organising time, trouble finishing tasks, restlessness, impulsive decisions and frequent interruptions during conversations.
In Majella’s case, the signs included difficulty focusing and staying organised, alongside a constant sense of physical restlessness. She described herself as someone who is nearly always moving, tapping her foot or preparing to begin the next activity. She also recognised a tendency to act quickly on impulses, particularly when spending money. These were not isolated moments but recurring patterns that became easier to understand once she viewed them through the perspective of her diagnosis.
Communication presented another revealing sign. Majella acknowledged that she sometimes interrupts people because she fears an important thought will disappear unless she expresses it immediately. What may appear to others as impatience or a failure to listen can, in her experience, come from the rapid movement of ideas and the difficulty of holding one thought while another person continues speaking. She has often found herself apologising and explaining that the interruption is not intended as disrespect.
There is also a quieter emotional dimension to her story. Majella recalled how difficulties at school and repeated criticism about talking too much affected her confidence. A person who spends years feeling disorganised, behind schedule or unable to meet ordinary expectations may gradually conclude that they are simply not trying hard enough. A diagnosis cannot change the past, but it can replace years of self-blame with a more compassionate understanding of how differently a person’s mind may process attention, stimulation and emotion.
Yet Majella does not describe ADHD only in terms of limitations. She has also spoken warmly about **hyperfocus**, an intense level of concentration that can emerge when she is deeply interested in a project. While painting her dot artwork, she may become so absorbed that several hours pass almost unnoticed. She has similarly connected this capacity for intense focus with creative achievement, including completing her book in a remarkably concentrated period.
That balance is what makes her disclosure so valuable. Majella is not presenting ADHD as a fashionable label, an excuse or a weakness. Instead, she is describing a different way of thinking—one that may bring restlessness, overstimulation and impulsivity, but can also produce enthusiasm, creativity and extraordinary determination. She has learned that taking on too many projects can leave her exhausted or stressed, so she now pays closer attention to sleep, personal boundaries and the need to withdraw into quiet surroundings when life becomes overwhelming.
Above all, Majella O’Donnell’s honesty offers reassurance to older adults who may have spent a lifetime questioning certain parts of themselves. Her experience does not mean that every restless, forgetful or energetic person has ADHD; only a qualified professional can provide a proper assessment. It does, however, remind readers that understanding can arrive at any age—and that receiving a diagnosis later in life may become not an ending, but the beginning of greater patience, self-knowledge and peace.
