Art therapy, a form of creative arts therapy, is increasingly recognized as a powerful tool for
psychological healing and emotional expression. This paper examines the evolution, theoretical
foundations, modalities, techniques, and clinical applications of art therapy across diverse populations and
settings. Drawing from both historical and contemporary perspectives, it examines how visual art can
facilitate emotional expression, trauma recovery, and mental health rehabilitation. The discussion
incorporates neuroscience research, psychodynamic theory, and cross-cultural considerations,
emphasizing the therapeutic benefits of non-verbal communication in art-making. Specific attention is
given to art therapy’s effectiveness in treating post-traumatic stress, depression, anxiety, and
neurodegenerative conditions, as well as its role in physical rehabilitation. Furthermore, this review
identifies gaps in qualitative meta-synthesis and calls for further interdisciplinary research. The findings
affirm that art therapy is not merely a supplementary treatment but a vital component of holistic care
models.
